WBBM (780kHz) – brandedNewsradio 105.9 WBBM – is a commercialall-newsAM radio station licensed to serveChicago, Illinois. Owned byAudacy, Inc., its studios are located atTwo Prudential Plaza in theChicago Loop, while the station's transmitter—diplexed with sister stationWSCR—is in the nearby suburb ofBloomingdale.
WBBM is aClass A station that broadcasts on aclear-channel AM frequency, powered with 35,000 watts by day and 42,000 watts at night, using anon-directional antenna. Its daytime signal provides at least grade B coverage to most of the northern two-thirds of Illinois (as far south asSpringfield) as well as large portions ofWisconsin,Iowa,Michigan andIndiana. Its city-grade coverage reaches as far north asMilwaukee. At night, WBBM can be heard across much of North America under favorable conditions, but is strongest in theMidwest.
In addition to a standardanalog transmission, WBBM broadcasts overHD Radio using thein-band on-channel standard,[4] is simulcast overWCFS-FM (105.9),[5] and is available online viaAudacy.
The most-common "program" on WBBM is a live rolling "news wheel" that begins at the top of each hour, structured into segments of news,traffic,weather, sports, and business updates fromBloomberg Radio. The scheduling of these segments is similar to that of several co-owned all-news stations includingKNX in Los Angeles,KCBS in San Francisco andWWJ in Detroit. This news wheel can be interrupted for breaking local or national news events that necessitate longer-form coverage.
WBBM is the Chicago affiliate station for theNotre Dame Fighting Irish football team.
Other programs featured on WBBM include:Noon Business Hour;At Issue, public affairs interviews with Craig Dellimore;CBS News Weekend Roundup; old-time radio programWhen Radio Was; audio portions of60 Minutes andFace the Nation.
WBBM also broadcasts 60-second light segments throughout the day, such asReal Estate Feature,Made in Chicago,Innovation Minute,Eating Right, among others. These segments are also available aspodcasts. Current on-air staff includes:Cisco Cotto, Keith Johnson,Nick Young, Lisa Fielding, Bernie Tafoya, Craig Dellimore, Mai Martinez, Andy Dahn, Rachel Pierson, Nancy Harty and Rob Hart.
WBBM was first licensed on January 31, 1924, to the Frank Atlass Produce Company at 110 Park Place inLincoln, Illinois.[6][7] The station's primary founder, 29-year-old Harry Leslie "Les" Atlass, had extensive earlier radio experience. In 1911, he had reportedly constructed a simple spark transmitter set.[8] Three years later, his then 11-year-old younger brother, Ralph, constructed an apparently unlicensed amateur radio station at the family home,[9] that was described as "chief wireless station" of the newly formed Lincoln United Wireless Association.[10]
With the April 1917 entrance of the United States intoWorld War I the federal government took full control of the radio industry, and it became illegal for civilians to operate radio transmitters and receivers.[11] After the conclusion of the war, the civilian radio restrictions were lifted.[12][13] Les Atlass' continuing interest in radio led in mid-1923 to his obtaining a license to operate an amateur radio station, 9DFC.[14]
Although the original spark radio transmitters were only capable of producing the dots-and-dashes ofMorse code, the development ofvacuum tube transmitters made audio transmissions practical. In the early 1920s, this led to the introduction of organized broadcasting, and by the end of 1922, over 500 broadcast stations were operating in the United States. Amateur radio stations were not permitted to make broadcasts intended for the general public. However, during April 1923, Les Atlass, in conjunction with theLincoln Courier newspaper, broadcast local election results over 9DFC, claiming as a technicality that instead of a prohibited public broadcast, he was merely transmitting information to a second amateur, which by chance (and through newspaper publicity) others might overhear.[2]
A few months later, Atlass procured a proper broadcasting station license with thecall sign WBBM, which made its debut on the evening of February 6, 1924,[2] transmitting on 1330 kHz.[7] The station's call letters had been randomly assigned from an alphabetic list maintained by the Department of Commerce, and during the inaugural broadcast, Atlass adopted a representative slogan of "We Broadcast Better Music".[2] Over the years, additional slogans would include "We Broadcast Broadmoor Music",[15] "World's Best Broadcast Medium",[16] and "Where Better Broadcasts Materialize".[17]
WBBM's time in Lincoln was brief. In mid-February 1924, it was announced that the Frank Atlass Produce Company, the family business where Les Atlass was president, had been sold, and he was preparing to move to Chicago. The last reported broadcast in Lincoln occurred on April 14, after which the station was dismantled, and its equipment shipped to Les Atlass' newly purchased Chicago home.[2] The station was officially deleted a few months later.[18]
Shortly after moving to Chicago, Les Atlass returned to the airwaves, and received a new license for a broadcasting station operated from his home at 7421 Sheridan Road, again with the call letters WBBM and transmitting on 1330 kHz, now with himself as the licensee.[20]
In 1925, station ownership was transferred to the Atlass Investment Company, with the station located at 1554 Howard Street, now transmitting with 1,500 watts.[21] On June 4, 1925, studios and transmitter were moved to the Broadmoor Hotel in Chicago'sRogers Park neighborhood. "95.99%" of the station's programming was devoted to music during this period,[16] including live musical broadcasts aired from a small studio in the lobby of the hotel. In 1926, theStewart-Warner corporation leased the station's full schedule, and began producing all of its programming.[22]
On June 15, 1927, WBBM moved to 770 kHz with 1,000 watts, sharing time with Chicago stations WAAF (nowWNTD) and WJBT.[23] Later in the year, power was increased to 5,000 watts.[6] On November 11, 1928, under the provisions ofGeneral Order 40, theFederal Radio Commission reallocated frequencies on the AM broadcasting band. WAAF was reassigned to 920 kHz, while WBBM and WJBT remained at 770 kHz, with the frequency now designated a "clear channel" assignment. WJBT's license was acquired by the Atlass Investment Company, and the two stations were consolidated as WBBM-WJBT, although the latter call sign was rarely, if ever, used. Its transmitter was moved toGlenview, Illinois, and its studios were moved to theWrigley Building.[6] Powers for clear channel stations could potentially be up to 50,000 watts, and WBBM's was increased to 10,000 watts in 1928 and 25,000 watts the following year.[6]
The station began a long association with theColumbia Broadcasting System (CBS) on September 27, 1928, when it joined as Chicago's secondnetwork affiliate. WMAQ (nowWSCR) had joined the network at its launch one year earlier.[17] CBS bought a controlling interest in WBBM in 1929,[24] and in 1931 it purchased the remaining station stock. Les Atlass remained at the station, while Ralph left and purchased stationWLAP, then inLouisville.[25]
On May 15, 1933, the station discontinued the WJBT dual call letter usage and reverted to just WBBM, after the Federal Radio Commission requested that stations using only one of their assigned call letters drop those that were no longer in regular use.[26]
As part of the November 11, 1928, AM band reorganization,KFAB inLincoln, Nebraska, had also been assigned to transmit on 770 kHz. WBBM and KFAB were far enough apart to allow concurrent operation during the daytime, but their longer range nighttime signals required coordination to avoid mutual interference. Initially, the stations established a timesharing agreement for nighttime hours. However, in early 1932, KFAB switched network affiliation from theNBC Red Network toCBS. With much of their evening programming the same, the two stations establishing simultaneous "synchronized" broadcasting of their common network programming.[27] The synchronized operation began on January 27, 1934.[28]
In 1945, WBBM broadcast "Five after the Hour", written by Les Weinrott.[29][30]
WBBM's power was increased to 50,000 watts in 1935.[6] In March 1941, as part of the implementation of theNorth American Regional Broadcasting Agreement (NARBA), both WBBM and KFAB were shifted to 780 kHz. After theattack on Pearl Harbor and the resulting U.S. entry intoWorld War II, there was an increase in air traffic atNaval Air Station Glenview. TheNavy asked WBBM to move its towers to a new location. As a result, the station's towers and transmitter were moved toItasca, Illinois, on May 1, 1942.[6] During World War II, much of WBBM's programming was devoted to the war effort.[22][31][32]
In 1948, KFAB was relocated toOmaha, and was also reassigned to 1110 kHz, freeing up WBBM to begin operating full-time on 780 kHz, ending the nighttime synchronized broadcasts.[33] In 1956, WBBM's studios were moved to North McClurg Court, with the rest of CBS's Chicago operations, where it remained until moving toTwo Prudential Plaza in 2006.[6][34] Les Atlass held various senior level management positions with WBBM and CBS until his retirement November 29, 1959, on his 65th birthday. He died the next year.[35]
Beginning in the 1950s, as network programming moved from radio to television, WBBM maintained a personality-basedmiddle of the road (MOR) format until 1964. At that point, it eliminated music and switched to anews/talk format. WBBM adopted its current all-news format on May 6, 1968, (after co-ownedWCBS in New York City switched to all news in 1967, andKNX in Los Angeles made the change in the spring of 1968).[36][37] The station was theflagship station of theChicago Bears from 2000 through 2022, and in its history has also airedChicago White Sox baseball games andChicago Blackhawkshockey games.
Over the years, WBBM fended off competition from other all-news stations that were attempted in the Chicagoradio market:McLendon-owned WNUS-AM-FM (1390 AM, nowWGRB and 107.5 FM, nowWGCI-FM),NBC's WNIS-FM (nowWKQX) andGroup W'sWMAQ (nowWSCR), which came under the CBS umbrella whenWestinghouse Electric Corporation purchased CBS in 1995.
From the 1950s through the 90s, WBBM had been in a spirited battle with rival news/talk/sports stationWGN for the position of the No. 1 radio station in the Chicago market. In the June 2009 ratings period, as estimated byArbitron, WGN held a slight edge over WBBM inPPM-metered listener ratings. However, since the fall of 2009, WBBM has maintained a lead while WGN's listenership began to decline.
Another challenge to WBBM's news radio domination came from Merlin Media, operated by former Tribune Company executiveRandy Michaels. Michaels purchased FM stationWKQX (the successor to WNIS-FM) in June 2011 with plans to switch formats to all-news asFM News 101.1, but in a preemptive move, CBS Radio launched a simulcast of WBBM overWCFS-FM that August 1. Previously, WBBM had been simulcast over WCFS'sHD2subchannel.[5]
The FM station's call letters were retained and should not be confused withWBBM-FM; WCFS-FM's formeradult contemporary format moved to the HD2 channel (until 2020), effectively switching signals with WBBM's audio.
On June 5, 2014, theChicago Cubs announced that theflagship station for theirradio broadcasts would be moved fromWGN to WBBM for the 2015 season under a 7-year deal. Cubs games were only broadcast on WBBM's AM feed; while the games were being played, WCFS-FM continued to broadcast WBBM's regular all-news programming uninterrupted.[38]
The arrangement lasted only one season; after co-ownedsports radio stationWSCR lost theWhite Sox toWLS for the 2016 season, an option was invoked which moved the Cubs to WSCR, giving the sports station another Chicago baseball team.[39][40][41] Interestingly, WLS only aired White Sox games for two seasons, ending in 2017, the White Sox relocated to WGN.
On February 2, 2017, CBS agreed to merge CBS Radio withEntercom, the fourth-largest radio broadcaster in the United States. The sale was conducted using aReverse Morris Trust to avoid a tax liability. While CBS shareholders retained a 72% ownership stake in the combined company, Entercom was the surviving entity, separating the WBBM radio stations (both 780 andFM 96.3) plus WCFS-FM fromWBBM-TV. The merger was approved on November 9, 2017, and was consummated on November 17.[42][43][44][45]
Despite the ownership change, WBBM radio and WBBM-TV maintain a partnership, with WBBM radio making use of some WBBM-TV local news and weather reporting. On March 1, 2018, Entercom launched a new website for WBBM alone on the company'sRadio.com portal, breaking it off from the former CBS Chicago portal.
Shortly after the move of the transmitter to the WSCR site, WBBM adjusted its news wheel for some segments for the first time in decades, presumably due to lengthening traffic reports and the adjustment of some ad breaks. The sports news segment moved to :16/:46, with business news coverage moving to :23/:53 past the hour, and hourly feature segments moving to :21 past the hour.[46]
TheCOVID-19 pandemic had a major effect on the station's daily operations, with only three people at a time in the station's newsroom and most of the station's anchors and news writersremote working. Traffic reports were temporarily reduced, the station's sportscasts were reduced, and some airshifts, mainly overnights, did not feature traffic reports, with some news hours pre-recorded with only reference to the minutes rather than anchors being live, though breaking news in overnight hours was still covered live.[47] Entercom changed its name to Audacy on March 30, 2021.
In 2018, WBBM was granted an FCCconstruction permit to move its transmitter to WSCR's tower site inBloomingdale. That allowed Entercom to sell the Itasca transmitter site to commercial and residential land developers.[48][49][50]
WBBM's power was reduced to 35,000 watts during the day and 42,000 watts at night, from the previous 50,000 watt signal it had maintained since 1935. Entercom engineers say the reduction in transmitting power will not be apparent to most listeners, except in some fringe areas.[49][50] The move was completed on July 18, 2019, with the previous transmitter inItasca, Illinois, coming down shortly thereafter.[51] Despite the reduction in power, WBBM is still considered aClass A station broadcasting on aclear channel frequency.[52]
