It was owned by General Tire along with WNAC radio (680 AM, now WRKO), flagship of the Yankee Network, a New England regional radio network. General Tire had purchased the Yankee Network in 1943. WNAC first broadcast from studios at 21 Brookline Avenue (which had also been home to WNAC radio and the Yankee Network) before moving to its current facilities at 7 Bullfinch Place near Government Center in 1968. In 1950, General Tire bought the West Coast regional Don Lee Broadcasting System. Two years later, it bought the Bamberger Broadcasting Service (WOR-AM-FM-TV in New York City) and merged its broadcasting interests into a new division, General Teleradio. General Tire bought RKO Radio Pictures in 1955 after General Tire found RKO's film library would be a perfect programming source for WNAC and its other television stations. The studio was merged into General Teleradio to become RKO Teleradio; after the film studio was dissolved, the business was renamed RKO General in 1959. WNAC-TV was originally a CBS affiliate, but shared ABC programming with WBZ-TV until 1957 when (the original) WHDH-TV signed on channel 5. WNAC-TV also had a secondary affiliation with the Paramount Television Network; in fact it was one of that that company's strongest affiliates, carrying Paramount programs such as Time For Beany, Dixie Showboat, Hollywood Reel, and Armchair Detective. WNAC-TV switched affiliations with WHDH in 1961 and joined ABC. It stayed with ABC until 1972, when channel 5 lost its license. The owners of the station that replaced it, WCVB-TV, planned to air more local programming than any other station in the country, heavily preempting CBS programming in the process. CBS was not pleased at the prospect of massive preemptions on what would have been its second-largest affiliate and largest affiliate on the East Coast. It immediately moved back to WNAC, leaving WCVB to affiliate with ABC. However, WNAC utilized the version of the circle 7 logo it had adopted in 1973 until 1977, when ABC complained it was infringing on its trademark, and it began using a Times-Serif-Italic "7". In 1980, a stylish, strip-layered "7" was introduced, which ended up being the last logo redesign under RKO General ownership. Two legendary Boston TV personalities had shows on WNAC: Louise Morgan, who hosted a talk show and was known as "New England's First Lady of Radio and Television", and Ed McDonnell, who as the costumed (as an astronaut) character "Major Mudd", hosted a popular children's show in the 1960s and early 1970s.
