Abstract

Television reporting records are accessed and processed to generate frequency specific reach values and device frequencies for creatives (e.g., television advertisements). The device frequencies indicating the number of times a creative was presented by use of a particular viewing device. The frequency specific reach values indicating the number of unique viewing devices that were used to present the creative a specified number of times. Estimating frequency specific reach values and device frequencies for a creative for a viewing population. The estimated frequency specific reach values and device frequencies for the viewing population are based on known viewing pattern data for multiple creative airings from a sample of the viewing population (e.g., a subset of the viewing population) and estimated viewing pattern data for the airings for the viewing population.

Description

BACKGROUND
• This disclosure relates to television advertising.
• Viewing information about creatives, e.g., television advertisements, presented by display devices, e.g., televisions, can be collected by viewing surveys in which members of a viewing population provide information about their viewing patterns; or by viewing devices, e.g., set top boxes, that automatically collect and transmit viewing pattern information to a collection entity. For example, for multiple airings of a particular creative, the number of times the creative was presented (impressions) can be determined based on anonymized viewing information collected through viewing surveys and/or viewing devices, and creative airing information (e.g., creative airing times and corresponding airing channels). To gauge the exposure of the creative or advertising campaign, e.g., a group of related creatives, to the viewing population advertisers look to viewership metrics such as impression figures, the number of times a particular device was used to present the creative (“device frequency”); and, for each unique device frequency (or group of unique device frequencies), the number of devices having that unique device frequency (“frequency specific reach value”); collectively referred to as “exposure data.”
• Typically, the viewing information collected from the viewer surveys and/or the viewing devices represents the viewing patterns of only a fraction of the viewing population. When viewing information is available only from a sample group of the viewing population, exposure data for the entire viewing population can be estimated based on the exposure data derived from the known viewing information of the sample group. Such estimation provides advertisers a more complete representation of the actual exposure of the creative. However, the accuracy of the estimated exposure data for the viewing population is dependent on both the accuracy of the exposure data for the sample group and the technique employed to estimate the data from the sample group to the viewing population.
SUMMARY
• In general, the subject matter of this specification relates to systems and methods for determining frequency specific reach values and device frequencies for creatives.
• One aspect of the subject matter described in this specification can be embodied in a system having a processing device and software stored on a computer readable medium which has instructions that can be executed by the processing device. Execution of the instructions cause the processing device to access television reporting data. The television reporting data includes viewing identifiers identifying viewing devices; creative identifiers identifying creatives that were presented by use of the viewing devices; and time data identifying times at which the creatives were presented by use of the viewing devices. The viewing identifiers, creative identifiers and time data are associated to identify, for each viewing device, the creatives presented by use of the viewing device and the times at which the creatives were presented. Execution of the instructions also cause the processing device to define frequency bins, each frequency bin corresponding to a frequency at which a creative is presented by use of a unique viewing device; and cause the processing device to process the television reporting data to generate device frequency data and frequency specific reach data. The device frequency data include device frequencies that quantify, for each viewing device, a frequency that each creative was presented by use of that viewing device during a reporting period. The frequency specific reach data include frequency specific reach values that quantify, for each creative and each frequency bin, a number of viewing devices that were used to present the creative at a frequency corresponding to the frequency bin. Execution of the instructions also cause reach and frequency reporting data to be generated, the reach and frequency reporting data detail creative exposure and include the frequency specific reach data and the device frequency data. Access to the reach and frequency reporting data is provided to television advertisers.
• Another aspect of the subject matter described in this specification can be embodied in a method that includes the actions of accessing television reporting records from a television reporting data store. Each television reporting record including a viewing identifier identifying a viewing device; a creative identifier identifying a creative that was presented by use of the viewing device; and time data identifying times at which the creative was presented by use of the viewing device. The viewing identifier, creative identifier and time data are associated to identify the creatives presented by use of the viewing device and the times at which the creative was presented. The method also includes defining frequency bins, each frequency bin corresponding to a frequency at which a creative is presented by use of a unique viewing device. The method further includes processing the television reporting records to generate device frequency data and frequency specific reach data. The device frequency data include device frequencies that quantify, for each viewing device, a frequency that each creative was presented by use of that viewing device during a reporting period. The frequency specific reach data include frequency specific reach values that quantify, for each creative and each frequency bin, a number of viewing devices that were used to present the creative at a frequency corresponding to the frequency bin. The method also includes generating reach and frequency reporting data that include the frequency specific reach data and the device frequency data detailing creative exposure. The method further includes providing access to the reach and frequency reporting data to television advertisers.
• Still another aspect of the subject matter described in this specification can be embodied in a method that includes the actions of accessing device frequency data that include device frequencies and frequency specific reach data that include frequency specific reach values from a reach and frequency data store. The device frequencies and the frequency specific reach values are based on multiple airings of a creative, each airing defining a unique creative time slot in which the creative was aired. The method includes calculating the number of total reported impressions of the creative for all airings based on the device frequencies and the frequency specific reach values. The method further includes for each airing, calculating the number of estimated impressions of the creative and calculating a number of total estimated impressions for all airings based on the numbers of estimated impressions for each airing. The method also includes calculating a scale factor based on the number of total estimated impressions and the number of total reported impressions and adjusting the device frequency data and frequency specific reach data according to the scale factor. The method further includes generating adjusted reach and frequency reporting data including the adjusted frequency specific reach data and the adjusted device frequency, and providing access to the adjusted reach and frequency reporting data to television advertisers.
• Yet another aspect of the subject matter described in this specification can be embodied in a system having a processing device and software stored on a computer readable medium having instructions executable by the processing device. Execution of the instructions cause the processing device to access device frequency data that include device frequencies and frequency specific reach data that include frequency specific reach values. The device frequencies and the frequency specific reach values are based on multiple airings of a creative, each airing defining a unique creative time slot in which the creative was aired. Execution of the instructions also cause the processing device to calculate a number of total reported impressions of the creative for all airings based on the device frequencies and the frequency specific reach values. For each airing, the number of estimated impressions of the creative are calculated. Execution of the instructions further cause the processing device to calculate the number of total estimated impressions for all airings based on the numbers of estimated impressions for each airing, to calculate a scale factor based on the number of total estimated impressions and the number of total reported impressions, and to adjust the device frequency data and frequency specific reach data according to the scale factor. Adjusted reach and frequency reporting data that include the adjusted frequency specific reach data and the adjusted device frequency data detailing creative exposure are generated. Execution of the instructions also cause access to the adjusted reach and frequency reporting data to be provided to television advertisers.

DETAILED DESCRIPTION
• §1.0 Television Advertisement System Overview
• FIG. 1 is a block diagram of an exampletelevision advertisement system100. Thetelevision advertisement system100 can, for example, deliver relevant content items, e.g., television advertisements/creatives, to viewers to facilitate operator monetization of programming and quantification of advertisement delivery to target markets. A creative can be, for example, a video portion of a television advertisement. The video portion of the advertisement can include audio and text. The creative can be shown separately from a television program in the form of a television commercial, or can be shown concurrently with a television program in the form of an overlay or text stream on a portion of a television display. For convenience, advertisements and creatives are collectively referred to as “advertisements” herein.
• Thetelevision advertisement system100 can, for example, be implemented on one or computer servers, and can provide and receive data over a network. Example networks include local area networks (LANs), wide area networks (WANs), telephonic networks, and wireless networks (e.g., 802.11x compliant networks, satellite networks, cellular networks, etc.). Additionally, thetelevision advertisement system100 can, for example, communicate over several different types of networks, e.g., the Internet, a satellite network, and a telephonic network.
• In general, thetelevision advertisement system100 can receive television advertisements and advertisement campaign data from anadvertiser140, e.g. an entity that provides television advertisements, such as a commercial entity that sells products or services, an advertising agency, or a person. Thetelevision advertisement system100 can facilitate the provisioning of television advertisements to atelevision provider120, e.g., an entity that facilitates the delivery of a television broadcast to viewers, such as cable provider, a digital satellite provider, a streaming media provider, or some other media provider.
• Thetelevision advertisement system100 can also, for example, obtain anonymized impression data related to viewing devices130a-130n. Example viewing devices130 include set top boxes, digital video recorders and tuners, and other television processing devices that facilitate the viewing of the television signal on a television device. For example, logs related to viewing device130 activity, e.g., set top box logs, can be anonymized to remove personal information related to viewing activities and provided to thetelevision advertisement system100. In another implementation, such information can be provided by theprovider120, or by a third party.
• Impressions can, for example, be measured statistically. An impression can be a household impression, e.g., the airing of an advertisement in household and independent of the number of televisions in a household. If the advertisement is presented by use of a viewing device in the household, one household impression can be recorded. Other impression types can also be used. For example, impressions can be generated by a program rating percentage, e.g., a percentage of viewership in measurable households; or by a program share percentage, e.g., a percentage of viewership in active measured homes; or by some other statistical measurement.
• By way of another example, impressions can be measured by an analysis of activity logs of the viewing devices130. For example, a household may have three viewing devices130, and at a given time two of the devices130 may be tuned to a first channel and the third device may be tuned to a second channel. If a first advertisement airs on the first channel and a second advertisement airs on the second channel, impressions can be generated for each viewing device130.
• An impression can be dependent on a television channel tune status when an advertisement airs on a channel. For example, an impression can occur when a viewing device130 is tuned to a broadcast stream in which an advertisement is inserted, and the viewing device130 remains tuned to the broadcast stream for N consecutive seconds during the actual display time of the insertion. For example, an impression can be defined as a viewing device130 remaining tuned to a broadcast stream for five seconds after the advertisement begins to air. Alternatively, an impression can be defined as a viewing device130 tuned to a broadcast stream when an advertisement is airing and remaining tuned to the broadcast stream for five seconds after tuning to the broadcast stream. Other tune times can also be used.
• Likewise, other impression types can also be used. For example, an impression can be based on an advertisement exposure, e.g., a brief exposure of an advertisement, or a full viewing of the advertisement, of a threshold viewing in between, e.g., five seconds, or five seconds of the first fifteen seconds; or a percentage of the advertisement viewed, etc.
• In an implementation, thetelevision advertisement system100 can also include one or more data stores to store television advertisements and associated data, e.g., performance data related to the television advertisements, log data from the viewing devices related to the viewing patterns of the audience, etc. In one implementation, thetelevision advertisement system100 includes a televisionadvertisement data store102, acampaign data store104, and a viewing devicelog data store106.
• The televisionadvertisement data store102 can, for example, include advertisements that can be broadcast or aired during an advertisement spot. Example television advertisements include video advertisements, banner advertisements, overlay advertisements, such as logos, URLs, dynamic pricing information for an advertisement, etc., and other advertisements that can be used to convey information visually and/or aurally during a television broadcast.
• Thecampaign data store104 can include, for example, advertising campaign information for multiple advertisers. Each campaign may include, for example, a campaign identifier identifying an advertising campaign. Each campaign identifier can be associated with one or more advertisement identifiers (creative identifiers) to identify advertisements associated with the advertising campaign. For example, a game system manufacturer may have a holiday season game console advertising campaign with two advertisements, one advertisement for a handheld gaming console and one advertisement for a desktop gaming console.
• The viewing devicelog data store106 can include, for example, data logs from viewing devices130, e.g., set top boxes, satellite receivers, etc. Thelog data store106 can include reporting data that identifies channel tunes, e.g., a channel identifier to which the viewing device was tuned, such as may occur when the viewing device130 is processing video data to record and/or display, and channel tune times, e.g., the times that the viewing device was tuned to a channel. Other data can also be included, e.g., key presses of remote devices associated with the viewing devices130, commands received by the viewing devices130, etc. For example, if the viewing device130 is a digital video recorder, the log data can include a list of recorded programs, and for each recorded program a record that indicates whether the recorded program has been played back, and the actions taken during playback, such as fast forwarding or skipping commercials can be included.
• The televisionadvertisement data store102,campaign data store104, and viewing devicelog data store106 can be implemented separately or in combination. For example, in one implementation, theadvertisement data store102,campaign data store104 and logdata store106 can be implemented in a single advertisement database. Other combinations and/or subcombinations can also be used.
• Thetelevision advertisement system100 can include anadvertisement distribution engine110, areporting engine112, and a reach andfrequency engine114. Theadvertisement distribution engine110, reportingengine112, and reach andfrequency engine114 can, for example, be distributed among a plurality of computer devices, e.g. server computers communicating over a network, or can be implemented on a single computer, e.g., as multiple threads on a server computer. Other implementation architectures can also be used. Theadvertisement distribution engine110, reportingengine112, and reach andfrequency engine114 can, for example, be implemented in software, such as executable object code, interpreted script instructions, or in combinations of executable and interpreted instructions. Other software and/or hardware implementations can also be used.
• Theadvertisement distribution engine110 can, for example, be configured to provide approved advertisements to thetelevision provider120. In one implementation, the advertisements are provided to thetelevision provider120 in advance of airing the advertisements. In some implementations, after receiving a request for any new advertisements to be downloaded for airing by theprovider120, thetelevision advertisement system100 can, for example, label the download with a particular ID that can be used later to identify the advertisement and thedistribution engine110 can deliver the advertisement to theappropriate provider120.
• Thereporting engine112 can, for example, receive advertisement report information from theprovider120 and determine whether the selected television advertisement aired based on the advertisement report information. For example, an advertisement may not air due to a programming irregularity, e.g., a sporting event going beyond a scheduled broadcast, an interruption to scheduled programming due to breaking news, etc. In an implementation, thereporting engine112 can process reporting logs, e.g., set top box logs, from viewing devices130 to determine advertisement impressions and/or false positive impressions.
• The reach andfrequency engine114 can, for example, generate frequency specific reach values and device frequencies for advertisements and/or advertising campaigns, and generate reach and frequency reporting data (e.g., reports that graphically and/or textually represent the frequency specific reach data and device frequency data).
• For example, the reach andfrequency engine114 can derive frequency specific reach values and device frequencies based, in part, on the anonymized viewing pattern information from the viewing devices130 included in thelog data106 and/or from the processed reporting logs from thereporting engine112. The reach andfrequency engine114 can also, for example, estimate frequency specific reach values and device frequencies for viewing populations with incomplete reporting records, e.g., a viewing population having a number of viewing devices that do not report viewing pattern information.
• The derivation of device frequencies and frequency specific reach values from thelog data106 is explained with reference to Table 1, which is populated with data derived from the viewing pattern information reported by threeviewing devices1,2, and3:

  	TABLE 1
  		Viewing	Viewing	Viewing
  		Device
  1	Device 2	Device 3
  	Airing A	X	X
  	Airing B	X	X	X
  	Airing C	X	X

• An airing is a unique advertisement time slot for a particular channel in which an advertisement is aired. Table 1 includes data for one advertisement that was aired three times: airings A, B, and C and according to Table 1,viewing devices1 and2 were used to present the advertisement three times (each presented the advertisement for airings A, B, and C) and viewing device3 was used to present the advertisement one time (airing B). The device frequency of a viewing device is the number of times that an advertisement was presented by use of that viewing device during a reporting period. Based on the information in Table 1 for the three-airing reporting period, the device frequency forviewing devices1 and2 is three and the device frequency for viewing device3 is one, as shown on Table 2:

  	TABLE 2
  		Viewing	Viewing	Viewing
  		Device
  1	Device 2	Device 3
  	Device Frequency	3	3	1

• A frequency specific reach value is the number of viewing devices that were used to present an advertisement at frequency corresponding to a frequency bin. A frequency bin corresponds to a frequency, e.g. number of times, at which an advertisement is presented by use of a unique viewing device130. For example, based on the information in Table 3, the frequency specific reach value associated withfrequency bin1, corresponding to a frequency of one, is one. Thus only one unique viewing device (viewing device3) was used to present the advertisement only one time. The frequency specific reach value associated withfrequency bin2, corresponding to a frequency of two, is zero. Thus no viewing devices were used to present the advertisement only two times. The frequency specific reach value associated with frequency bin3, corresponding to a frequency of three, is two. Thus two unique viewing devices (viewing devices1 and2) were used to present the advertisement only three times.

  §2.0 Example Detailed Reach and Frequency System Architecture and Operation
• FIG. 2 is a block diagram of an example television advertisement reach andfrequency processing system200 used in the television advertisement system ofFIG. 1.
• The reach andfrequency processing system200 can facilitate access to television reporting data stored in a televisionreporting data store210. The television reporting data can, for example, be derived from thelog data106 and/or impression information from thereporting engine112; or accessed through a third party that provides the data.
• The television reporting data include television reporting records that includeviewing identifiers220 identifying viewing devices130;advertisement identifiers230 identifying advertisements that were presented by use of the viewing devices130; andtime data240 identifying times at which the advertisements were presented by use of the viewing devices130. The television reporting records can be based on data from the viewing devicelog data store106 and advertisement airing information including times during which advertisements were aired and the corresponding channels which aired the advertisements. For example, a television reporting record may include:

  	V_ID00001111:OperatorID=1243.HeadendID=22.InsertionZone=243. InsertionID

  =53432934.Channel=123.Start=4:04:52pm.End=4:06:39pm

• where V_ID00001111 is ananonymized viewing identifier220, OperatorID, HeadendID, and InsertionZone are identifiers related to aparticular operator120 and corresponding geographic location, InsertionID is anadvertisement identifier230, Channel is a channel identifier, Start is a first tune time indicating when the viewing device130 tuned to the channel identified by the channel identifier, and End is a second tune time indicating when the viewing device130 tuned out of the channel identified by the channel identifier. In part, the InsertionID identifies an advertisement that was aired during the time between the first and second tune times by use of the viewing device130 identified by theviewing identifier220.
• Thus, theviewing identifiers220,advertisement identifiers230 andtime data240 can be associated to identify, for each viewing device130, the advertisements presented by use of the viewing device130 and the times at which the advertisements were presented. For example, for a reporting period it can be determined from the television reporting data (e.g. stored in the television reporting data store210), the number of impressions for a particular advertisement resulting from the use a particular viewing device130.
• The television reporting records can also indicate that a television advertisement was not presented by use of a viewing device130 if the television reporting record indicates that the viewing device was tuned to a different channel during the airing of an advertisement. For example, a television reporting record can indicate that a particular viewing device was tuned to channel59 during a time period that included the start time 4:04:52 PM and end time 4:06:39 PM, and thus the advertisement identified by the advertisement identifier 53432934 was not shown by use of the viewing device.
• The reach andfrequency engine114 can also be configured to define frequency bins, as discussed with reference to Table 3. In some implementations, frequency bins are not restricted to an integer frequency value and may correspond to a range of frequencies, e.g., a frequency bin may define a minimum frequency value and a maximum frequency value. For example, a frequency bin may define a minimum frequency value of fifty-one and a maximum frequency value of fifty-five. Thus all viewing devices used to present the advertisement at least fifty-one times and not in excess of fifty-five times during a reporting period are associated with the frequency bin.
• The range of frequencies corresponding to individual frequency bins for an advertisement can also vary. For example, the first fifty frequencies may each correspond to one frequency bin (e.g., one integer frequency value corresponding to one frequency bin), the next fifty frequencies may correspond to frequency bins having a range of five frequencies, and the final 100 frequencies may correspond frequency bins having a range of twenty-five frequencies, as depicted on Table 4:

  TABLE 4
  Frequencies	frequencies/bin	Number of Frequency Bins

  1-50	1	50
  51-100	5	10
  101-200	25	4

• As such, for television reporting data including a wide frequency distribution of frequencies at which an advertisement is presented by use of a unique viewing device130, the frequencies corresponding to frequency bins can be defined to limit the number of frequency bins, e.g., for data size management.
• The reach andfrequency engine114 can also be configured to perform operations to process the television reporting data to generate frequencyspecific reach data315 anddevice frequency data300.FIG. 3A shows example content of device frequency data. For example, the device frequency data can be generated by the reach andfrequency engine114.FIG. 3B shows example content of frequency specific reach data. For example, the frequency specific reach data can be generated by the reach andfrequency engine114.
• The frequencyspecific reach data315 anddevice frequency data300 can be stored in reach andfrequency data store260. Thedevice frequency data300 can include device frequencies for each viewing device130 that quantify the number of times each viewing device130 was used to present a particular advertisement and/or an advertising campaign.
• For example,device frequency data300 can include device frequencies forviewing device1,viewing device2, through viewing device n indicating thatviewing device1,viewing device2, and viewing device n presentedadvertisement1 245 times, 312 times, and 168 times; respectively. As indicated by the hierarchical path “Campaign1/Advertisement1,advertisement1 belongs toCampaign1. The frequency data can be aggregated according to campaigns, for example, if an advertising campaign is associated with multiple advertisements then the device frequency of a particular viewing device for the advertising campaign is the sum of the device frequencies for that viewing device for each of the advertisements associated with advertising campaign. In some implementations, thedevice frequency data300 can include device frequencies for multiple advertising campaigns, such asadvertising campaign1 through advertising campaign n.
• Frequencyspecific reach data315 can include frequency specific reach values for each frequency bin for a particular advertisement and/or advertising campaign. For example, frequencyspecific reach data315 indicate that 345 viewing devices were used to presentadvertisement1 at a frequency corresponding tofrequency bin1, 270 viewing devices were used to presentadvertisement1 at a frequency corresponding tofrequency bin2, and 56 viewing devices were used to presentadvertisement1 at a frequency corresponding to frequency bin n.
• Further, if an advertising campaign is associated with multiple advertisements then the frequency specific reach value for a particular frequency bin for the advertising campaign is the sum of the frequency specific reach values for that frequency bin for each of the advertisements associated with advertising campaign. In some implementations, the frequencyspecific reach data315 can include frequency specific reach values for multiple advertising campaigns, such asadvertising campaign1 through advertising campaign n.
• In various implementations the reach andfrequency engine114 can also aggregate the number of the viewing devices130 quantified for each frequency specific reach value to determine advertisement reach data (creative reach data) to identify a total number of unique viewing devices that were used to present the advertisement (creative), i.e., the overall reach of the advertisement. The advertisement reach data can, for example, be stored in the advertisementreach data store250.
• As mentioned above, the frequencyspecific reach data315 and thedevice frequency data300 can be stored in the reach andfrequency data store260. The reach andfrequency data store260 can, for example, be adatabase260 stored on a memory device such as a computer hard drive and the frequency specific reach data and device frequency data for a particular advertisement airing can be stored in thedatabase260 according to theadvertisement identifier230 associated with the advertisement. Further, the frequency specific reach data and device frequency data can also be stored according to advertising campaign identifiers.
• The reach andfrequency engine114 can also be configured to access demographic data from, for example, ademographic data store270. The demographic data may be correlated to the television reporting data and/or thelog data106 to relate the television reporting data and/or logdata106 to demographic information about the viewing population. For example, the demographic data may relateanonymized viewing identifiers220 to geographic profiles of the viewing population, to age profiles of the anonymized viewers associated with the viewing devices, etc. Based on the demographic data, the frequency specific reach data and device frequency data can be filtered according to desired demographics. For example, the frequency specific reach data and device frequency data can be filtered based on the geographic profile of the viewing population to determine frequency specific reach values and device frequencies for a specific geographic region.
• The television reporting data may not include relations between advertisements and advertising campaigns, as described above with reference toFIGS. 3A and 3B. Thus, in some implementations, the reach andfrequency engine114 can access thecampaign data104 to identify campaign identifiers and associations between campaign identifiers and advertisement identifiers. Based on the accessedcampaign data104, the reach andfrequency engine114 can process the reporting data to generate the Example data ofFIGS. 3A and 3B.
• FIG. 4 shows example data reported by viewing devices for use by the television advertisement reach and frequency processing system ofFIG. 2.
• An advertisement was aired three times; airings A, B and C. Each airing A, B and C has a respectivepotential viewing population412,422 and432; a reportingpopulation415,425 and435; and animpressed population417,427, and437; respectively. The viewing population corresponds to the total number of viewing devices130 in a region. The reporting population corresponds to the number of viewing devices130 in the viewing population for which reporting records are received correlated to the time of the airing (regardless of whether the viewing device130 was used to present the advertisement). Reporting populations need not be the same for each airing, and often differ for each airing. The impressed population corresponds to the number of viewing devices130 in the reporting population that were used to present the advertisement for an airing (i.e., viewing devices130 that account for an impression).
• For a set of n advertisement airings there are on the order of (2ˆn−1) combinations of how viewing devices130 in a viewing population could present the advertisement. Further for airings A, B and C each viewing device may have been in the reporting population for one airing (A, B or C), two airings (A+B, B+C or A+C) or all three airings (A+B+C). The number of the reporting population for each of these combinations must be known to determine frequency specific reach data and device frequency data for the potential viewing population. However, each airing combination could have a distinct reporting population, and all airing combinations would have to be calculated individually to estimate frequency specific reach data and device frequency data.
• For example, the reporting population for airing combination A+B cannot be derived just by knowing the individual reporting populations for airings A and B. To determine the reporting population for airing combination A+B the intersection of the reporting populations for airing A and airing B must be calculated, i.e., the overlap in the reporting populations between airings A and airing B. This calculation becomes prohibitive for a large number of advertisement airings and large reporting populations.
• As discussed above, frequency specific reach data and device frequency data can be generated based on data derived from data logs from viewing devices130 in a reporting population. However, it is often desirable to estimate frequency specific reach data and device frequency data for the potential viewing population. Because the reporting data are not available from all viewing devices130 in the viewing population and not all reporting records arrive at once (there can be reporting delays up to a week), frequency specific reach data and device frequency data from the reporting population must be projected onto the viewing population. In other words, the known frequency specific reach data and device frequency data derived from the reporting population must be extrapolated to generate frequency specific reach data and device frequency data for the viewing population.
• In various implementations, estimation of frequency specific reach data and device frequency data for the viewing population can be calculated, as explained below, based on a scale factor derived from the number of total reported impressions for all airings and the number of total estimated impressions for all airings.
• First the number of total reported impressions must be determined to derive the scale factor. The reach andfrequency engine114 can access the frequency specific reach data and device frequency data (for the reporting population) and calculate a number of total reported impressions for all airings of an advertisement (or advertising campaign) during the reporting period. For example, the reach andfrequency engine114 can calculate the number of total reported impressions of the advertisement and store the results in a total reportedimpressions data store280. The number of total reported impressions can be calculated, for example, based on the device frequency data and the frequency specific reach data, according to Equation 1:$\begin{array}{cc}\#\mathrm{total}\mathrm{reported}\mathrm{impressions}=\sum _{X=1}^n\mathrm{fsrv}\left(\mathrm{frequency\_bin}\mathrm{\_X}\right)*\mathrm{frequency\_X}& \mathrm{Equation}1\end{array}$
• where fsrv(frequency_bin_X) is the frequency specific reach value associated with frequency bin X and frequency_X is the frequency that corresponds to frequency bin X. For example, with reference to Table 3, the total number of reported impressions according toEquation 1 is seven, e.g., (1*1)+(0*2)+(2*3)=7, as shown in Table 5:

• Second, the number of estimated impressions must be determined. The reach andfrequency engine114 can calculate the number of estimated impressions for each airing, which is needed to calculate the number of total estimated impressions for all airings. The number of estimated impressions for each airing can be calculated, for example, based on the number of reported impressions for an airing (i.e., the impression generating population), the number of reporting records for that airing (i.e., the reporting population), and the number of the viewing population. The calculated number of estimated impressions for each airing for each viewing population (there could be multiple viewing populations) can be stored the estimatedimpressions data store290.
• In some implementations, the number of estimated impressions for each airing can be calculated, for example, by multiplying the number of the viewing population by the ratio of the number of reported impressions for that airing divided by the number of reporting records for that airing according to Equation 2:$\begin{array}{cc}\#\mathrm{estimated}\mathrm{impressions}\text{/}\mathrm{airing}=\frac{\#\mathrm{reported\_impressions}}{\#\mathrm{reporting\_records}}*\left(\#\mathrm{viewing\_population}\right)& \mathrm{Equation}2\end{array}$
  If the airing of the advertisement occurred in multiple viewing populations then the number of estimated impressions for that airing for all viewing populations can be determined by calculating the number of estimated impressions for the airing for each viewing population and then summing the estimated impressions for the airing from all viewing populations.
• The number of estimated impressions for each airing can also be determined through other techniques. For example, the number of estimated impressions for each airing can be determined through the use of probability density functions. Further, a number of estimated impressions for an airing can be selected from a probability distribution that satisfies a particular threshold or confidence value, i.e., a minimum probability or likelihood.
• With reference to Table 1 (assuming a viewing population of fifteen for all airings) the number of estimated impressions for airing A is according toEquation 2, (⅔)*15=10. Further assume two additional reporting records have been received for Airing B, each additional record indicating the advertisement was not presented. The numbers of estimated impressions for airings B and C can be calculated in a similar manner. The results are depicted on Table 6:

  TABLE 6
  	reported	reporting	viewing	estimated
  	impressions	records	population	impressions

  Airing A	2	3	15	10
  Airing B	3	5	15	9
  Airing C	2	3	15	10

• Next, to determine the scale factor the reach andfrequency engine114 can calculate the number of total estimated impressions for all airings, for example, based on the numbers of estimated impressions for each airing and store the number of total estimated impressions for all airings in a total estimatedimpressions data store295. The number of total estimated impressions for all airings can be calculated, for example, by summing the numbers of estimated impressions for each airing, according to Equation 3:$\begin{array}{cc}\#\mathrm{total}\mathrm{estimated}\mathrm{impressions}\mathrm{for}\mathrm{all}\mathrm{airings}=\sum _{X=1}^n\#\mathrm{estimated\_impressions}\mathrm{\_airing}\left(X\right)& \mathrm{Equation}3\end{array}$
• where # estimated_impressions_airing (X) is the number of estimated impressions for a particular airing X of airings X=1-n. With reference to Table 6, the number of total estimated impressions can be calculated, for example, according to Equation 3, e.g., 10+9+10=29, as shown on Table 7:

  	TABLE 7
  	# estimated_impressions_airing(A)	10
  	# estimated_impressions_airing(B)	9
  	# estimated_impressions_airing(C)	10
  	# total estimated impressions for all airings	29

• Finally, the reach andfrequency engine114 can calculate the scale factor that can be used to estimate frequency specific reach data and device frequency data for a potential viewing population based on the calculated frequency specific reach data and device frequency data for the reporting population. For example, the scale factor is the ratio of the number of total estimated impressions for all airings divided by the number of total reported impressions for all airings, according to Equation 4:$\begin{array}{cc}\mathrm{scale}\mathrm{factor}=\frac{\#\mathrm{total\_estimated}\mathrm{\_impressions}}{\#\mathrm{total\_reported}\mathrm{\_impressions}}& \mathrm{Equation}4\end{array}$
• For example, with reference to Tables 5 and 7, the number of total reported impressions for all airings is seven and the number of total estimated impressions for all airings is twenty-nine. Accordingly, the scale factor is 29/7=4.14, as depicted on Table 8:

  TABLE 8
  		scale
  # total_estimated_impressions	# total_reported_impressions	factor
  29	7	4.14

• The reach andfrequency engine114 can be configured to adjust the frequency specific reach data and device frequency data according to the scale factor to estimate the frequency specific reach data and device frequency data for the viewing population. For example, the adjusted frequency specific reach data and adjusted device frequency data for an advertisement can be calculated by multiplying the scale factor by the frequency specific reach value associated with each frequency bin, according to Equation 5:
  adjusted frequency specific reach data and device frequency data=scale factor*fsrv(frequency_bin_—X)  Equation 5
• With reference to Tables 3 and 8, the adjusted frequency specific reach data and device frequency data, for example according to Equation 5, are 4.14 viewing devices are estimated to have presented the advertisement one time (e.g., 4.14*1=4.14) and 8.28 viewing devices are estimated to have presented the advertisement three times (e.g., 4.14*2=8.28), as shown on Table 9:

  TABLE 9
  	fsrv		adjusted R&F
  	(frequency_bin_X)	scalefactor	data

  frequency_bin_1

  	1	4.14	4.14
  frequency_bin_2	0	4.14	0
  frequency_bin_3	2	4.14	8.28

• The data set used to generate Table 9 is for exemplary purposes and represents only a fraction of the actual data that would be used to determine frequency specific reach data and device frequency data in typical television advertisement systems.
• FIG. 5 is an example histogram based on frequency specific reach data and device frequency data. For example, frequency specific reach data and device frequency data from Table 1 can be used to constructhistogram500. In some implementations, the reach andfrequency engine114 in the television advertisement reach andfrequency processing system200 can generate reach and frequency reporting data and/or adjusted reach and frequency reporting data including the frequency specific reach data and the device frequency data, and the adjusted frequency specific reach data and the adjusted device frequency data, respectively. Such reporting data can be stored in a reach and frequencyreporting data store297. The reach and frequency reporting data and/or adjusted reach and frequency reporting data can be presented by use ofhistogram500 or other types of graphical and/or textual representations (of the underlying frequency specific reach data and the device frequency data, and/or adjusted frequency specific reach data and adjusted device frequency data). Further, access to the reach and frequency reporting data and/or adjusted reach and frequency reporting data can be provided to advertisers to illustrate the exposure of the advertisement during the reporting period.
• The reach of the advertisement can readily be determined from thehistogram500. The reach or overall reach (the total number of unique viewing devices that were used to present the advertisement) can be determined, for example, according to Equation 6:$\begin{array}{cc}\mathrm{reach}=\sum _{X=1}^n\mathrm{fsrv}\left(\mathrm{frequency\_bin}\mathrm{\_X}\right)& \mathrm{Equation}6\end{array}$
  With reference tohistogram500, the reach of the advertisement for the reporting population is three: 1 (fsrv(frequency_bin_1))+0 (fsrv(frequency_bin_2))+2 (fsrv(frequency_bin_3)). The reach can be stored, for example, in the advertisementreach data store250.
• FIG. 6 is a flow diagram of an example process for generating frequency specific reach data and device frequency data. For example, theprocess600 can be implemented in the television advertisement reach andfrequency processing system200 ofFIG. 2.
• Television reporting records are accessed (610). For example, reach andfrequency engine114 accesses television reporting data stored in the televisionreporting data store210, the television reporting data including television reporting records.
• A plurality of frequency bins are defined (620). For example, reach andfrequency engine114 defines a plurality of frequency bins, the frequency bins similar to the frequency bins described above with reference to Table 4.
• The television reporting records are processed to generate device frequency data and frequency specific reach data (630). For example, the reach andfrequency engine114 processes television reporting data including television reporting records to generate frequency specific reach data including frequency specific reach values and device frequency data including device frequencies similar to the data stored in reach andfrequency data store260.
• Reach and frequency reporting data including the frequency specific reach data and the device frequency data are generated (640). For example, the reach andfrequency engine114 in the television advertisement reach andfrequency processing system200 can generate reach and frequency reports representing and based on the reach and frequency reporting data, similar to that stored in reach and frequencyreporting data store297.
• Access to the reach and frequency reporting data are provided to television advertisers (650). For example, the television advertisement reach andfrequency processing system200 can provide access to reach and frequency reports to television advertisers to inform the television advertisers about the exposure of the creative.
• Optionally, for each advertisement, the number viewing devices quantified for each frequency specific reach value are aggregated to determine advertisement reach data (660) for the advertisement. The advertisement reach data identifies the number of unique viewing devices that were used to present the advertisement. For example, reach andfrequency engine114 can aggregate the number of viewing devices130 quantified for each frequency specific reach value to determine advertisement reach data similar to that stored in the advertisementreach data store250. Consider Table 1, reproduced below:

  TABLE 1
  	Viewing Device 1	Viewing Device 2	Viewing Device 3
  Airing A	X	X
  Airing B	X	X	X
  Airing C	X	X

• Theprocess600 can be implemented, in part, according to the following set of example instructions for each advertisement airing:

  device_frequency_so_far = current_device frequency(VD_id)
  if device_frequency_so_far > 0

  then fsrv(device_frequency_so_far) =

  fsrv(device_frequency_so_far) − 1

  incremented_device_frequency = device_frequency_so_far + 1

  current_device_frequency(VD_id) = incremented_device_frequency

  fsrv(incremented_device_frequency) =

  fsrv(incremented_device_frequency) + 1

  
  where:
• current_device_frequency(VD_id) is the current device frequency of a viewing device associated with viewing identifier VD_id;
• device_frequency_so_far is the current device frequency of a viewing device;
• fsrv(device_frequency_so_far) is the frequency specific reach value associated with the frequency bin corresponding to the frequency of device_frequency_so_far; incremented_device_frequency is the incremented value of device_frequency_so_far; and
• fsrv(incremented_device_frequency) is the frequency specific reach value associated with the frequency bin corresponding to the frequency of incremented_device_frequency.
• Processing the data on Table 1 forviewing device1 and airing A by the exemplary instructions recited above yields the following results: device_frequency_so_far=0 (the current viewing device frequency forviewing device1 is zero asviewing device1 has not yet been used to present the advertisement); as device_frequency_so_far is not greater than zero the incremented_device_frequency=0+1=1; the current_device_frequency (VD1)=1; and the fsrv(1)=0+1=1. The results are shown on Table 10:

• Viewing device3 did not present the advertisement for airing A and thus the data for the advertisement is not changed.
• Processing the television reporting data on Table 1 forviewing device1 and airing B by the exemplary instructions recited above yields the following results: device_frequency_so_far=1; as device_frequency_so_far is greater than zero the fsrv(1)=fsrv(1)−1=2−1=1; the incremented_device_frequency=1+1=2; current_device_frequency(VD1)=2; and the fsrv(2)=0+1=1.

• FIG. 7 is a flow diagram of anexample process700 for processing television reporting records to generate frequency specific reach data and device frequency data.
• A television reporting record is selected (710). For example, reach andfrequency engine114 can select a television reporting record from television reporting data stored in the televisionreporting data store210.
• A viewing device and advertisement (creative) are identified from a viewing identifier and advertisement identifier in the television reporting record (720). For example, reach andfrequency engine114 identifies a viewing device130 and advertisement based on theviewing identifier220 andadvertisement identifier230 from the television reporting data.
• A current device frequency for the viewing device is identified (730). The current device frequency defines the number of times the viewing device has been used to present the advertisement based on the selected television reporting records. Thus, the current device frequency will change when an existing but yet to be selected television reporting record indicates that the viewing device was again used to present the advertisement. For example, reach andfrequency engine114 can identify the current device frequency for the viewing device130.
• It is determined whether the current device frequency indicates that the viewing device has been used to present the advertisement (740). For example, reach andfrequency engine114 can determine if the current device frequency indicates that the viewing device130 has been used to previously present the advertisement. If the current device frequency of the viewing device130 is, for example, greater than zero then the viewing device130 has been used to present the advertisement.
• If the viewing device is determined to have been used to present the advertisement, then a first frequency bin corresponding to the current device frequency is identified (750). For example, reach andfrequency engine114 can identify a frequency bin, e.g., a frequency bin discussed with reference to Table 4, associated with a frequency corresponding to the current device frequency.
• Further, the frequency specific reach value associated with the first frequency bin will be decremented (755). For example, reach andfrequency engine114 can decrement the frequency specific reach value associated with the first frequency bin to indicate that the current device frequency of the viewing device does not correspond to the frequency associated with the first frequency bin.
• The current device frequency is incremented (760). For example, reach andfrequency engine114 can increment the current device frequency.
• A second frequency bin corresponding to the incremented current device frequency is identified (765). For example, reach andfrequency engine114 can identify the second frequency bin.
• The frequency specific reach value associated with the second frequency bin is incremented (770). For example, reach andfrequency engine114 can increment the frequency specific reach value associated with the second frequency bin to indicate that that the incremented current device frequency of the viewing device corresponds to the frequency associated with the second frequency bin.
• If the viewing device is determined to have not been used to present the advertisement, then the current device frequency is incremented (780). For example, reach andfrequency engine114 can increment the current device frequency.
• A frequency bin corresponding to the incremented current device frequency is identified (785). For example, reach andfrequency engine114 can identify a frequency bin corresponding to the incremented current device frequency.
• The frequency specific reach value associated with the frequency bin is incremented (790). For example, reach andfrequency engine114 can increment the frequency specific reach value associated with the frequency bin.
• FIG. 8 is a flow diagram of anexample process800 for estimating frequency specific reach data and device frequency data.
• Device frequency data and frequency specific reach data are accessed (810). For example, reach andfrequency engine114 can access the device frequency data and frequency specific reach data from reach andfrequency data store260.
• The number of total reported impressions of the advertisement for all airings is calculated based on the device frequencies and frequency specific reach values (820). For example, reach andfrequency engine114 can calculate the number of total reported impressions of the advertisement for all airing based on the device frequencies and frequency specific reach values included in reach andfrequency data store260.
• For each airing of the advertisement, the number of estimated impressions of the advertisement is calculated (830). In some implementations, the number of the viewing population and the ratio of the number of reported impressions for that airing to the number of reporting records for that airing are multiplied to calculate the number of estimated impressions for the airing (835). For example, reach andfrequency engine114 can calculate the number of estimated impressions of the advertisement for each airing and, in some implementations, can calculate the number of estimated impressions for each airing by multiplying the number of the viewing population and the ratio of the number of reported impressions for that airing to the number of reporting records for that airing.
• The number of total estimated impressions for all airings of the advertisement is calculated based on the numbers of estimated impressions for each airing (840). In various implementations, the number of total estimated impressions for all airings is calculated by summing the numbers of estimated impressions for each airing (845). For example, reach andfrequency engine114 can calculate the number of total estimated impressions for all airings based on the numbers of estimated impressions for each airing, and in various implementations, can calculate the number of total estimated impressions for all airings by summing the numbers of estimated impressions for each airing.
• In some implementations, optionally, the number of total estimated impressions for all airings is accessed (837) instead of calculated. For example, reach andfrequency engine114 can access the number of total estimated impressions for all airings from, for example, an entity that collects, reports, and/or analyzes television viewing pattern data.
• A scale factor can be calculated based on the number of total estimated impressions and the number of total reported impressions (850). In some implementations, the scale factor is calculated by dividing the number of total estimated impressions by the number of total reported impressions (855). For example, reach andfrequency engine114 can calculate the scale factor based on the number of total estimated impressions and the number of total reported impressions and, in some implementations, can calculate the scale factor by dividing the number of total estimated impressions by the number of total reported impressions.
• The device frequency data and frequency specific reach data can be adjusted according to the scale factor (860). In some implementations, the device frequency data and frequency specific reach data are adjusted by multiplying the frequency specific reach values by the scale factor (865). For example, reach andfrequency engine114 can adjust the device frequency data and frequency specific reach data according to the scale factor and, in some implementations, can adjust the data by multiplying the frequency specific reach values by the scale factor according to, for example, Equation 5.
• Adjusted reach and frequency reporting data that include the adjusted frequency specific reach data and the adjusted device frequency data are generated (870). For example, the reach andfrequency engine114 intelevision advertisement system100 can generate the adjusted reach and frequency reporting data.
• Access to the adjusted reach and frequency reporting data can be provided to television advertisers (880). For example, the television advertisement reach andfrequency processing system200 can provide access to the adjusted reach and frequency reporting data to television advertisers to inform the advertisers about television advertisement exposure.
• The television industry typically evaluates advertisement viewership information over rolling seven or thirty-day periods. Thus, the frequency specific reach data and device frequency data can be calculated for these rolling periods. For example, consider that an advertisement has three airings; airing A on June 1st, airing B on June 11th and airing C on June 21st. Throughout June (and some of July), on each day a new set of thirty-day rolling frequency specific reach data and device frequency data is generated. For example, on June 2nd (the day after airing A) frequency specific reach data and device frequency data are generated for the advertisement. As there has only been one airing the data echoes the reported impressions for airing A. Over each of the next seven days (2nd-8th) the frequency specific reach data and device frequency data are updated as new viewing pattern data are reported from the viewing devices. The frequency specific reach data and device frequency data should remain stable for three days (9th-11th) until the day after the second airing (as all viewing pattern data should have been received).
• From the 12th to the 18th the frequency specific reach data and device frequency data for airings A and B are gradually refined as viewing pattern data are received. From the 19th to the 21st, frequency specific reach data and device frequency data should again remain stable. After the 22nd the frequency specific reach data and device frequency data are updated and refined as viewing pattern data are received through the 28th. The frequency specific reach data and device frequency data should be stable until July 2nd.
• After July 1st, the thirty-day period no longer includes airing A, so from then on frequency specific reach data and device frequency data reflect viewing pattern data for only airings B and C. Similarly on July 12th airing B is no longer included in the thirty-day reporting period, so the frequency specific reach data and device frequency data only reflect viewing pattern data from airing C. Finally by July 22nd airing C is no longer included in the thirty-day period so frequency specific reach data and device frequency data for the advertisement are no longer generated.
• Preferably the frequency specific reach data and device frequency data for each day are stored for a predetermined time, so in the above illustration approximately fifty sets of daily frequency specific reach data and device frequency data are stored for the rolling thirty-day reporting period. In general for any advertisement active over n days, n+30 sets of frequency specific reach data and device frequency data are generated for the thirty-day reporting period, and n+7 sets of frequency specific reach data and device frequency data for the seven-day reporting period. This permits the advertiser to review frequency specific reach data and device frequency data generated at various points during the reporting period.
