The Westinghouse Broadcasting Company, also known as Group W, was the broadcasting division of Westinghouse Electric Corporation. It owned several radio and television stations across the United States and distributed television shows for syndication.
Westinghouse Broadcasting was formed in the 1920s as Westinghouse Radio Stations, Inc. It was renamed Westinghouse Broadcasting Company in 1954, and adopted the Group W moniker on May 20, 1963. It was a self-contained entity within the Westinghouse corporate structure; while the parent company was headquartered in Pittsburgh, Pennsylvania, Westinghouse Broadcasting maintained headquarters in New York City. It kept national sales offices in Chicago and Los Angeles.
Group W stations are best known for using a distinctive corporate typeface, introduced in 1963, for their logos and on-air imaging. 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; Ray Larabie's freeware font "Anklepants" borrows heavily from the typeface and is occasionally used as a substitute. The font is also used in the video game Damnation.

The Westinghouse Electric and Manufacturing Company entered broadcasting with the November 2, 1920 sign-on of KDKA radio in Pittsburgh. 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 of Wilkinsburg, and founded in 1916 by Westinghouse assistant chief engineer Frank Conrad.
Westinghouse launched three more radio stations in 1921: WJZ, originally licensed to Newark, New Jersey, in September; WBZ, first located in Springfield, Massachusetts, in October; and KYW, originally based in Chicago, in November. WBZA in Boston, a station which shared WBZ's frequency and simulcasted WBZ's programming, signed on in November 1924.
Westinghouse was one of the founding owners of the Radio Corporation of America in 1919, and in 1926 RCA established the National Broadcasting Company, 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's Blue 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 to Philadelphia following a Federal Communications Commission-dictated frequency realignment. Westinghouse's next station was its first purchase: WOWO in Fort Wayne, Indiana joined the group in August 1936.
The North American Regional Broadcasting Agreement of 1941 saw all of Westinghouse's original stations move to their current dial positions. With WOWO's power increase to 50,000 watts later that year, the Westinghouse stations were now also clear-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 a grandfather clause. Among them, the four stations' nighttime signals blanketed almost all of the eastern half of North 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's Red Network while WOWO, which had a secondary affiliation with the Blue Network, fell back on its primary relationship with CBS. Westinghouse expanded to the West Coast in 1944 with its purchase of 5,000-watt KEX in Portland, Oregon, a station which also shared a frequency with WOWO. Westinghouse would increase KEX's power to 50,000 watts in 1948.
Later in the 1940s, Westinghouse moved on to develop FM and television stations as the FCC began to issue permits for those services. Westinghouse built FM 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 (now WLTJ) and the second WBZ-FM facility (now WMJX) 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 of WIND. In 1962 Westinghouse re-entered the New York market when it bought WINS, then a local Top-40 powerhouse. Having reached the FCC's then-limit of seven AM stations, Westinghouse sold KEX to actor and singer Gene Autry, and later decided to shut down WBZA and return its license to the FCC. In 1966 Westinghouse agreed to buy another top-rated music station, KFWB in Los Angeles.
On April 19, 1965 WINS dropped music and instituted a 24-hour, all-news format. KYW went all-news six months later on September 12, three months after Westinghouse regained control of the station (see The 1956 Trade with NBC, below). KFWB would adopt the format on March 11, 1968. 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-owned WBBM.
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, including KFBK in Sacramento, California; WNEW-FM in New York, KTWV in Los Angeles, and WMMR in Philadelphia. WOWO was sold to other interests in 1982 and WIND was spun off in 1985, two years before Group W bought WMAQ from NBC after that network announced it was closing its radio division.
Expansion into television
Westinghouse entered television on June 9, 1948 with the sign-on of WBZ-TV in Boston; it is the only television station to have been built by the company. Westinghouse's first station purchase was with WPTZ (now KYW-TV) in Philadelphia, in 1953. KPIX in San Francisco was bought in 1954; WDTV (now KDKA-TV) in Pittsburgh was added in 1955; and WAAM (now WJZ-TV) in Baltimore was purchased in 1957. Westinghouse's only other outright television station purchase was in Charlotte, North Carolina, where it purchased WRET-TV from Ted Turner in early 1980, and changed its call letters to WPCQ-TV. Turner used the proceeds from the sale of the Charlotte station to help him launch CNN.
The company also purchased cable TV system operator TelePrompTer in 1981, which it renamed Group W Cable the following year. The TelePrompTer acquisition also brought animation producer Filmation into the Group W fold. However, Westinghouse would leave the cable TV system business in 1986, and would later sell the Filmation library to L'Oréal in 1989. During that period, Group W was known in full as Westinghouse Broadcasting and Cable, Inc.
The 1956 trade with NBC
In June 1955 Westinghouse announced that it would sell its Philadelphia stations, KYW radio and WPTZ, to NBC. In exchange Westinghouse received NBC's Cleveland stations, WTAM radio and WNBK television, along with $3 million in compensation. The deal was approved in January 1956; one month later Westinghouse moved the KYW call letters to Cleveland and NBC renamed the Philadelphia stations WRCV (AM) and WRCV-TV. Both companies also transferred much of their respective management and some on-air personnel to their new cities. Most notably, both The Mike Douglas Show and the Eyewitness News format originated on KYW-TV during its tenure in Cleveland.
However, the ink had barely dried on FCC approval of the trade when the United States Department of Justice opened an investigation into the deal, on claims that NBC had employed extortion and coercion. 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 civil antitrust suit was filed against NBC and its parent company RCA, on behalf of Westinghouse in December 1956. During this ordeal NBC attempted to circumvent the investigation by trading the Philadelphia stations in return for RKO General's radio and television properties in Boston, which would have resulted in WBZ-TV losing its NBC affiliation to rival station WNAC-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. NBC appealed the ruling, extending the ordeal by another year, but to no avail. 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 station KYW-TV. And in a reversal of nine years prior, both NBC and Westinghouse relocated various personnel between both cities.
Later years in television
Throughout its history as an operator of television stations, Westinghouse Broadcasting had relationships with all three major networks. KYW-TV, WBZ-TV, and WPCQ-TV were NBC affiliates, KPIX and KDKA-TV were aligned with CBS, and WJZ-TV was an ABC station. All of Group W's stations were located within the top 40 television 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 in television syndication (see Syndication 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 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 on VHF. 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 (now WCNC-TV) to Odyssey Television Partners (later to become Renaissance Broadcasting) in 1985. 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.
Merger with CBS
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, the Fox Broadcasting Company agreed to a multi-year, multi-station affiliation deal with New World Communications, resulting in most of New World's stations switching to Fox. Among these stations were longtime CBS affiliates WJBK-TV in Detroit and WJW-TV in Cleveland.
To avoid being consigned to the UHF band in two major markets, CBS heavily courted ABC affiliates WXYZ-TV in Detroit and WEWS-TV in Cleveland. Both stations were owned by the E. 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 agreed to 10-year affiliation contracts with WEWS, WXYZ and four other Scripps stations.
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. 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 47 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. 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.
- On September 10, 1995, KYW-TV switched from NBC to CBS. CBS traded its previous Philadelphia station, WCAU-TV, to NBC in return for KCNC-TV in Denver and KUTV in Salt Lake City. CBS then traded controlling interest in KCNC and KUTV to Westinghouse in return for a minority stake in KYW-TV. (KCNC's station 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 massive capital gains tax bill if it sold WCAU to NBC outright.
- As a result of the trade, CBS-owned WCIX in Miami swapped channel locations with NBC-owned WTVJ. CBS and NBC traded their Miami broadcasting facilities to compensate each other for the loss of stations. WCIX changed its call letters to WFOR-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. 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&O's reached 21.8% prior to the purchase, and Group W reached 9.7%.)
A short time later, Westinghouse announced it was buying CBS outright, a transaction which closed in late 1995. 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 sell recently acquired WPRI-TV in Providence, Rhode Island due to a significant signal overlap with WBZ-TV. At the time, the FCC normally did not allow common ownership of stations with overlapping signals.
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. Excluding WMAQ (shut down in 2000 to allow all-sports WSCR 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 on November 17, 2017, with the merged entity taking Entercom's name; 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.
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 nonbroadcast properties. In 1997, Westinghouse changed its name to CBS Corporation and moved its headquarters to New York. In 1998, the company created a new licensing subsidiary under the Westinghouse Electric Corporation name. In this sense, the Westinghouse-CBS merger turned out to be a "wag the dog" transaction.
After selling off its nuclear assets to BNFL in 1999, CBS Corporation was merged into Viacom a year later, thus shutting down the Original Westinghouse for good. Viacom, however, changed its name to CBS Corporation in 2005 and spun off most of its cable and movie interests as a new Viacom. With a few exceptions, the current CBS Corporation holds the same television properties that the old CBS Corporation held prior to the Viacom merger, including the new Westinghouse. In 2017, CBS Corporation spun off its radio assets to Entercom. National Amusements retains majority control of both CBS and Viacom, while CBS Corporation shareholders hold 72% of Entercom's stock.
A few of the former Westinghouse radio stations still use the former Group W font today (e.g. KDKA, KYW, and WINS). WOWO, now owned by Pathfinder Communications Corporation, and two television stations, WJZ-TV and KPIX, continue to use this font as well. The other stations discontinued using the typeface early in the 21st century.

- 1 Westinghouse Broadcasting also acquired a construction permit for channel 20 in Chicago along with its purchase of WIND radio in 1956 but that station, intended to be called WIND-TV, never signed on. The permit was later donated to the Chicago Educational Television Association, which operated channel 20 as noncommercial educational WXXW from 1965 to 1974. The channel 20 allocation was occupied by WYCC, an educational station operated by the City Colleges of Chicago, from 1983 until 2017.
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. In the 1990s, it also went under the name of Westinghouse Productions. Many of these programs were also sold internationally (under the name of Westinghouse Broadcasting International).

End of Group W Productions
After the merger with CBS in 1996, Westinghouse acquired Ed Wilson and Bob Cook's MaXam Entertainment and merged it with Group W Productions and CBS Enterprises (including CBS Broadcast International) to form Eyemark Entertainment, with CBS Broadcast International acquiring the overseas rights to the Group W backlog. Eyemark was in turn folded into King World Productions following the latter company's acquisition by CBS in 2000. King World gained control of most of the Group W and Eyemark libraries from 2000 to 2005. These libraries are now controlled by CBS Television Distribution. The Filmation library and The George Michael Sports Machine are owned by NBCUniversal, Bob Vila's Home Again is owned by Bob Vila, and the 1987 Teenage Mutant Ninja Turtles series is now owned by Viacom with DVD rights licensed to Lionsgate Home Entertainment.
