TheWestinghouse Broadcasting Company, also known asGroup W, was thebroadcasting division ofWestinghouse Electric Corporation. It owned severalradio andtelevision stations across the United States and distributed television shows forsyndication.

Westinghouse Broadcasting was formed in the 1920s asWestinghouse Radio Stations, Inc. After expanding into television, it was renamed as Westinghouse Broadcasting Company in 1954, and adopted theGroup W moniker on May 20, 1963. It was a self-contained entity within the Westinghouse corporate structure; while the parent company was headquartered inPittsburgh, Pennsylvania, Westinghouse Broadcasting maintained headquarters inNew York City. It kept national sales offices inChicago andLos Angeles. After its merger withCBS in 2000, the majority of the broadcast assets today are owned byParamount Skydance Corporation.

Group W stations are best known for using a distinctive corporatetypeface, introduced in 1963, for their logos and on-air imaging.^[1][2] Similarly styled typefaces had been used on some non-Group W stations as well and several former Group W stations still use it today. The Group W corporate typeface has been digitized and released freely by John Sizemore;^[2]Ray Larabie's font "Anklepants^[3] borrows heavily from the typeface and is occasionally used as a substitute.^[4] The font is also used in the video gameDamnation.

Westinghouse Broadcasting was also well known for two long-running television programs, theMike Douglas Show andPM Magazine (calledEvening Magazine in Group W's core broadcast markets).

The Westinghouse Electric and Manufacturing Company entered broadcasting with the November 2, 1920, sign-on ofKDKA radio in Pittsburgh.^[5] The oldest surviving licensed commercial radio station in the United States, KDKA was an outgrowth of experimental station 8XK, a 75-watt station that was located in the Pittsburgh suburb ofWilkinsburg, and founded in 1916 by Westinghouse assistant chief engineerFrank Conrad.^[6]

Westinghouse launched three more radio stations between 1920 and 1921:WJZ,^[7] originally licensed toNewark, New Jersey;WBZ, first located inSpringfield, Massachusetts;^[8] andKYW, originally based inChicago.^[9] WBZA inBoston, a station which shared WBZ's frequency and simulcasted WBZ's programming, signed on in November 1924.^[8]

Westinghouse was one of the founding owners of theRadio Corporation of America (RCA) in 1919, and in 1926 RCA established theNational Broadcasting Company (NBC), a group of 24 radio stations that made up the first radio network in the United States. Westinghouse initially owned a 20 percent stake in NBC, and as a result, all of Westinghouse's stations became affiliates of NBC'sBlue Network when it was launched on January 1, 1927. Most of the Blue Network's programming originated at WJZ, which in 1923 had its license moved to New York City, and its ownership transferred to RCA.

In 1931, Westinghouse switched the call letters of its two Massachusetts stations, with WBZA moving to Springfield and WBZ going to Boston. The two stations had suffered from interference problems, though the Boston facility was the more powerful of the two. In 1934, KYW was moved from Chicago toPhiladelphia following aFederal Communications Commission-dictated frequency realignment.^[10] Westinghouse's next station was its first purchase:WOWO inFort Wayne, Indiana, joined the group in August 1936.^[11]

TheNorth American Regional Broadcasting Agreement of 1941 saw all of Westinghouse's original stations move to their current frequencies. With WOWO's power increase to 50,000watts later that year, the Westinghouse stations were now alsoclear-channel stations. A decade later, the FCC forbade common ownership of two or more clear channel stations with overlapping nighttime coverage, though the commission allowed Westinghouse to keep WBZ, KYW, KDKA, and WOWO together under agrandfather clause.^{[citation needed]} Among them, the four stations' nighttime signals blanketed almost all of the eastern half ofNorth America. Despite the assignments which resulted from NARBA, WBZA became a 1,000-watt daytime-only operation as it continued to share a frequency with WBZ.

The Westinghouse group survived the government-dictated split of NBC's radio division in 1943. WBZ/WBZA, KDKA, and KYW became affiliates of NBC'sRed Network while WOWO, which had a secondary affiliation with the Blue Network, fell back on its primary relationship withCBS. Westinghouse expanded to the West Coast in 1944 with its purchase of 5,000-wattKEX inPortland, Oregon,^[12] a station which also shared a frequency with WOWO. Westinghouse would increase KEX's power to 50,000 watts in 1948.^[13]

Later in the 1940s, Westinghouse moved on to develop FM and television stations as the FCC began to issue permits for those services. Westinghouse builtFM sister stations for WBZ/WBZA, KDKA, KYW, KEX, and WOWO, all of which were on the air by the end of the decade. FM radio was, initially, an unsuccessful venture for Westinghouse, and the company would silence most of its FM stations during the 1950s. Of the early Westinghouse FMs, only the original KDKA-FM (nowWLTJ) and the second WBZ-FM facility (nowWMJX) proved to be worth keeping, and Westinghouse sold those outlets in the early 1980s.

Moving back to AM radio, Westinghouse returned to Chicago with its 1956 purchase ofWIND.^[14] In 1962, Westinghouse re-entered the New York market when it boughtWINS, then a local Top-40 powerhouse, fromJ. Elroy McCaw.^[15] Having reached the FCC's then-limit of seven AM stations, Westinghouse sold KEX to actor and singerGene Autry,^[16] and later decided to shut down WBZA and return its license to the FCC.^[17] In 1966, Westinghouse agreed to buy another top-rated music station,KFWB inLos Angeles.^[18]

On April 19, 1965, WINS dropped music and instituted a 24-hour, all-news format.^[19] KYW went all-news six months later on September 12, three months after Westinghouse regained control of the station^[20] (seeThe 1956 Trade with NBC, below). KFWB would adopt the format on March 11, 1968.^[21] The three stations all prospered with their new formats, usually ranking among the five highest-rated stations in their markets. During the 1970s and 1980s, WIND also tinkered with a part-time news format, though it had little success against the dominant all-news station in Chicago, CBS-ownedWBBM.

In the 1970s, Westinghouse Radio also developed a prodigious reputation for its innovation in analytical techniques and tools for radio sales and buying. Using sophisticated mathematical modeling, the group promoted its "New Math Calculator" which became extremely popular in ad agencies for planning radio campaigns. This was no simple look-up table; it introduced innovative measures such as "reach index" and "gross cume" to operationalize its core models. Westinghouse later introduced an even more comprehensive tool, stylized as the "Numa Radio Planner". In the days before desktop computers, these "slide rules" were state-of-the-art in audience planning research.

Over the next quarter-century, Westinghouse would purchase several other radio stations, includingKFBK inSacramento, California;WNEW-FM in New York,KTWV in Los Angeles, andWMMR in Philadelphia.^[22] WOWO was sold to other interests in 1982^[23] and WIND was spun off in 1985,^[24] two years before Group W boughtWMAQ from NBC after that network announced it was closing its radio division.^[25]

Westinghouse entered television on June 9, 1948, with the sign-on ofWBZ-TV in Boston; it is the only television station to have been built by the company.^[26] Westinghouse's first station purchase was with WPTZ (nowKYW-TV) in Philadelphia, in 1953.^[27]KPIX inSan Francisco was bought in 1954;^[28] WDTV (nowKDKA-TV) in Pittsburgh was added in 1955;^[29][30] and WAAM (nowWJZ-TV) inBaltimore was purchased in 1957.^[31][32] Westinghouse's only other outright television station purchase was inCharlotte, North Carolina, where it purchased WRET-TV fromTed Turner in early 1980, and changed its call letters to WPCQ-TV.^[33] Turner used the proceeds from the sale of the Charlotte station to help him launchCNN.

In 1961, the company expanded into television production by launching television and radio distributor WBC Productions.^[34] In 1980, the company bought out a majority share of Home Theater Network fromDiversified Communications.^[35] The company also purchased cable TV system operatorTelePrompTer in 1981, which it renamed Group W Cable the following year. Also that year, the company formed Group W Satellite Communications to maintain operations of its satellite business through its TelePrompTer acquisition, as well as that of Home Theater Network.^[36] The TelePrompTer acquisition also brought animation producerFilmation into the Group W fold.^[37] However, Westinghouse would leave the cable TV system business in 1986, and would later sell the Filmation library toL'Oréal in 1989.^[38][39] During that period, Group W was known in full as Westinghouse Broadcasting and Cable, Inc.

In June 1955, Westinghouse announced that it would sell its Philadelphia stations, KYW radio and WPTZ, to NBC. In exchange Westinghouse received NBC'sCleveland stations,WTAM radio andWNBK television, along with $3 million in compensation.^[40] The deal was approved in January 1956;^[41] one month later Westinghouse moved the KYW call letters to Cleveland and NBC renamed the Philadelphia stations WRCV (AM) and WRCV-TV.^[42] Both companies also transferred much of their respective management and some on-air personnel to their new cities. Most notably, bothThe Mike Douglas Show and theEyewitness News format originated on KYW-TV during its tenure in Cleveland.

However, the ink had barely dried on FCC approval of the trade when theUnited States Department of Justice opened an investigation into the deal, on claims that NBC had employedextortion andcoercion.^[43] The Justice Department believed that NBC abused its power as a broadcast network by threatening to withhold or cancel affiliations with Westinghouse-owned stations unless the latter company agreed to the network's terms and participate in the trade. Specifically, it was determined that NBC threatened to drop its programming from both WPTZ and Boston's WBZ-TV; to withhold a primary affiliation from newly acquired KDKA-TV in Pittsburgh (that station would sign with CBS as a primary affiliate); and to withhold or pull an NBC affiliation from any other major-market station Westinghouse would purchase in the future. Based on these findings, a civilantitrust suit was filed against NBC and its parent company RCA, on behalf of Westinghouse in December 1956.^[44] During this ordeal NBC attempted to circumvent the investigation by trading the Philadelphia stations in return forRKO General's radio and television properties in Boston,^[45][46] which would have resulted in WBZ-TV losing its NBC affiliation to rival stationWNAC-TV; the proposed NBC-RKO station swap never materialized.

In August 1964, after a nearly eight-year-long investigation, the FCC ordered a reversal of the swap.^[47] NBC appealed the ruling, extending the ordeal by another year, but the ruling was upheld on appeal. Westinghouse was also allowed to keep the cash compensation from the original deal. When Westinghouse regained control of the Philadelphia stations on June 19, 1965, it restored the KYW calls to the radio station and renamed the television stationKYW-TV. And in a reversal of nine years prior, both NBC and Westinghouse relocated various personnel between both cities.^[48]

Throughout its history as an operator of television stations, Westinghouse Broadcasting had relationships withall three major networks. KYW-TV (in both Cleveland and Philadelphia), WBZ-TV, and WPCQ-TV were NBC affiliates, KPIX and KDKA-TV were aligned with CBS, and WJZ-TV was anABC station. All of Group W's stations were located within the top 40television markets.

Westinghouse's television stations were all known for their very deep connection to their home markets. They often pre-empted network programming in favor of local programs, and all of them carried programming produced by Group W, which was a major force intelevision syndication (seeSyndication programs, below). However, for the most part the networks did not seem to mind. Most of them were among their networks' strongest performers. KDKA-TV and WJZ-TV dominated their markets, while WBZ-TV and KPIX were solid runners-up.

The only exceptions were KYW-TV and WPCQ. KYW-TV had been one of Westinghouse's (and NBC's) crown jewels for many years, but faltered in the late 1970s and eventually became NBC's weakest major-market affiliate by the mid-1980s. Westinghouse found no success in the Charlotte market, as WPCQ-by far the smallest station ever owned by the company-remained an also-ran during its Group W years. Despite the record purchase price, Group W ran the station on a shoestring budget. Under Group W, WPCQ had a marginal signal, a minimal local news presence and a program schedule more typical of an independent station, with a large number of cartoons and second-hand syndicated programming. WPCQ was also a UHF network affiliate competing against two long-established network stations onVHF. It also had to deal with three longer-established NBC affiliates, on VHF channels from nearby cities, that were also available over-the-air in large parts of the Charlotte market. Westinghouse was able to escape Charlotte when it sold WPCQ (nowWCNC-TV) to Odyssey Television Partners (later to becomeRenaissance Broadcasting) in 1985.^[49] The subpar performance of KYW-TV and WPCQ was particularly embarrassing for NBC, as it came during a very prosperous period for the network as a whole.

Aside from WPCQ, Group W almost expanded into the country's top two markets; it emerged as a leading bidder for RKO General's independent stations WOR-TV (currentlyWWOR-TV) inSecaucus, New Jersey (serving New York City), and came to a deal to buy KHJ-TV (currentlyKCAL-TV) in Los Angeles. However, protracted legal issues that had dogged RKO General for years delayed the transfer of KHJ-TV, and Westinghouse ultimately withdrew its offer. They were also outbid for WOR-TV by a consortium ofCox Enterprises andMCA/Universal (though the former company dropped out over questions of who would be running the station).^[50][51] In 1987, Westinghouse attempted a bid for the station group handled by investment firmKohlberg Kravis Roberts, with six stations formerly held byStorer Broadcasting, but the deal ultimately fell through.^[52]

Within a year-long span during 1994–95, a series of surprising events occurred which not only changed the look of the television industry but also ended Westinghouse's uniqueness among television station operators.

In 1994, theFox Broadcasting Company agreed to a multi-year, multi-station affiliation deal withNew World Communications, resulting in most of New World's stations switching to Fox. Among these stations were longtime CBS affiliatesWJBK-TV inDetroit andWJW-TV in Cleveland.^[53]

To avoid being consigned to the UHF band in two major markets, CBS heavily courted ABC affiliatesWXYZ-TV in Detroit andWEWS-TV in Cleveland. Both stations were owned by theE. W. Scripps Company, who used this leverage to strike a similar multi-station affiliation deal of its own with ABC. Unwilling to risk losing two of its strongest and longest-standing affiliates, ABC and Scripps agreed to a 10-year affiliation contract with WEWS, WXYZ and threeotherstations.

One of these additional stations was Baltimore's then-NBC affiliate,WMAR-TV, which would displace that city's longtime ABC affiliate, Group W-owned WJZ-TV.^[54] ABC was initially skeptical of including WMAR in the deal; WJZ-TV had been one of ABC's strongest affiliates, and had been the dominant station in Baltimore for a quarter-century. In contrast, WMAR had been a ratings also-ran for over 30 years. However, Scripps demanded that WMAR be included if the deal was to go through. Well aware that there were few viable choices for replacement affiliates in Detroit or Cleveland, ABC gave in.

The loss of WJZ-TV's ABC affiliation did not sit well with Westinghouse. At the time, WJZ-TV had been affiliated with ABC for 46 years, longer than any station that wasn't owned by the network. Westinghouse sought an affiliation deal of its own, and after several months of negotiations with the other networks, Westinghouse agreed to affiliate its entire television unit with CBS.^[55] Under the terms of the deal, all five Group W stations would carry the entire CBS schedule with no pre-emptions except for local news emergencies (as noted above, prior to this, Group W stations were known for pre-empting selected programming of their affiliated networks with Group W-mandated content).

The deal resulted in a three-way transaction between Group W, CBS, and NBC, which unfolded between the summer of 1994 and the summer of 1995. The terms were as follows:

• In September 1994, KPIX and KDKA-TV ended their long-standing policies of pre-empting some CBS shows, and began carrying the entire CBS schedule with no pre-emptions. (KPIX however at the time aired CBS prime time programming an hour earlier than normal, a practice that continued until 1998.)
• On January 2, 1995, WJZ-TV and WBZ-TV switched from ABC and NBC, respectively, to CBS, whileWBAL-TV andWHDH-TV affiliated with NBC; WMAR-TV took on WJZ-TV's ABC affiliation.
• On September 10, 1995, at 1:00 a.m. EDT, KYW-TV switched from NBC to CBS. CBS traded its previous Philadelphia station,WCAU-TV, to NBC in return forKCNC-TV inDenver andKUTV inSalt Lake City, whileKUSA andKSL-TV affiliated with NBC andKMGH-TV affiliated with ABC. CBS then traded controlling interest in KCNC and KUTV to Westinghouse in return for a minority stake in KYW-TV. (KCNC'sstation history page erroneously implies that this trade was between NBC and Westinghouse.) The swap in Philadelphia was delayed when CBS discovered it would face a massivecapital gains tax bill if it sold WCAU to NBC outright.^[56]
  • As a result of the trade, CBS-owned WCIX inMiami swapped channels with NBC-ownedWTVJ. CBS and NBC traded their Miami broadcasting facilities to compensate each other for the loss of stations. WCIX changed its call letters toWFOR-TV, and CBS sold controlling interest in WFOR to Westinghouse.
• Westinghouse and CBS formed a joint venture that assumed ownership of KYW-TV, KCNC, KUTV and WFOR, with Westinghouse as majority owner.^[57] Giving Group W control of the venture allowed CBS to have some interest in its affiliates and avoid violating FCC rules at the time that forbade groups from owning TV stations that covered more than 25% of the country (CBS O&Os reached 21.8% prior to the purchase, and Group W reached 9.7%.)^[58]

A short time later, Westinghouse announced it was buying CBS outright, a transaction which closed in late 1995.^[59] As a condition of the merger, both CBS and Group W were forced to sell off several radio stations due to the FCC's then-current ownership limits. CBS also had to sellWPRI-TV inProvidence, Rhode Island (which was acquired in March 1995 and would swap affiliations withWLNE-TV one hour before KYW-TV assumed the CBS affiliation)^[60] due to a significant signal overlap with WBZ-TV, which provides a city-grade signal to much of the Providence market. At the time, the FCC normally did not allow common ownership of stations with overlapping signals, and would not even consider granting a waiver for a city-grade overlap; the FCC began to allow common ownership of stations with overlapping signals without a waiver in 2000.

Following the completion of the CBS takeover, the former Westinghouse Broadcasting operations took on the CBS name and identity, though the Group W name survived until the end of the 1990s as a holding company within the merged entity's structure. The Westinghouse-CBS merger resulted in several longtime rivals on the radio dials of New York City, Los Angeles, Chicago, and Philadelphia becoming sister stations.

From that point forward, however, Westinghouse proceeded to transform itself from its legendary role as a diversified conglomerate with a strong industrial heritage into a media giant. Over the next year, it sold off almost all of its non-broadcast properties. In 1997, Westinghouse changed its name to CBS Corporation and moved its headquarters to New York. Westinghouse's cable television network properties—consisting then ofThe Nashville Network (now the general-interestParamount Network) andCountry Music Television, which CBS/Westinghouse purchased fromGaylord Entertainment in 1996, and equity stakes inregional sports networksMidwest Sports Channel (now split intoFanDuel Sports Network North, serving Minnesota and theDakotas, andFanDuel Sports Network Wisconsin, both of which CBS purchased in conjunction with its 1992 acquisition of Midwest Television and its two stations,WCCO-TV inMinneapolis/St. Paul andWFRV-TV inGreen Bay) andHome Team Sports (nowMonumental Sports Network) in theBaltimore–Washington area—were consequently reorganized as CBS Cable (a name used prior by CBS Inc. for anarts-oriented basic cable channel it operated from October 1981 to December 1982). In 1998, the company created a new licensing subsidiary under theWestinghouse Electric Corporation name. In this sense, the Westinghouse-CBS merger turned out to be a "wag the dog" transaction.

After selling offits nuclear assets toBNFL in 1999, CBS Corporation was merged intoViacom in 2000, thus ending the corporate legacy of the original Westinghouse for good. TNN and CMT were consolidated into Viacom'sMTV Networks basic cable unit post-merger, with HTS being sold toComcast and Midwest Sports Channel being sold toNews Corporation shortly afterward. Viacom, however, changed its name toCBS Corporation at the end of 2005 and spun off most of its cable and movie interests asa new Viacom. With a few exceptions, the "new" CBS Corporation retained the same television properties that the old CBS Corporation held prior to the Viacom merger, including thenew Westinghouse. Theater chainNational Amusements, which had held controlling interest in the "old" Viacom since 1986, retained controlling interest in both the "new" CBS and Viacom.

Excluding WMAQ (shut down in 2000 to allow all-sportsWSCR to move to its old dial position) and KFWB (placed in a holding trust as a consequence of CBS's purchase of KCAL-TV; the trust divested the station in 2016), all of the former Group W radio stations were part of CBS Radio until its merger with Entercom (nowAudacy, Inc.) on November 17, 2017. While the merged company took Entercom's name, CBS shareholders held controlling interest in the enlarged Entercom. Following the merger, one of the former Group W stations, WBZ, was spun off to iHeartMedia. CBS had previously announced in 2016 that it had been looking to leave the radio business.

In 2019, Viacom and CBSreunited as ViacomCBS (renamedParamount Global in 2022), with National Amusements as the majority shareholder.^[61][62] Paramount Global and National Amusements thenmerged withSkydance Media to form theParamount Skydance Corporation in 2025.

Currently, only one station continues to use the classic Group W font: radio station WOWO (owned by Pathfinder Communications Corporation). The other stations gradually discontinued using the typeface during the 21st century.

Some of their best-known programs were syndicated and seen in primetime and early/late fringe through its syndication division, Group W Productions, which was originally known as WBC Productions until 1968.^[63] It was originally founded in 1961 to sell syndication of radio and television programming.^[34] Many of these programs were also sold internationally (under the name of Westinghouse Broadcasting International). In 1992, the Westinghouse Broadcasting International unit has signed a deal withMitsubishi to represent the catalog for the Japanese market.^[64]
