WNAC-TV

WNAC-TV, channel 7, was a television station located in Boston, Massachusetts, United States. The station was owned by RKO General. Originally established in 1948, WNAC-TV signed off for the final time at 1:00 a.m. on May 22, 1982, due to improprieties by its parent company; it was replaced that morning with WNEV-TV (now WHDH), which operates on a separate license. The station was Boston's original CBS television affiliate; except for a period from 1961 to 1972 during which it was an ABC affiliate, WNAC-TV would remain with CBS until its replacement with WNEV-TV. History Origins WNAC-TV first signed on the air on June 21, 1948 as the second television station in Boston after WBZ-TV (channel 4), which had debuted 12 days earlier. Channel 7 originally operated as a CBS affiliate but also carried some programs from ABC and the DuMont Television Network. The station was originally owned by General Tire, along with WNAC radio (then at 1260 AM, frequency now occupied by WBIX; later moved to 680 AM, now WRKO), which served as the flagship station of the Yankee Network, a regional New England radio network. General Tire had purchased the Yankee Network in 1943. WNAC-TV first broadcast from the WNAC/Yankee Network's studios at 21 Brookline Avenue, near Fenway Park, before RKO moved its Boston operations to new facilities near Government Center at 40 Hawkins Street (later renamed 7 Bulfinch Place) in 1968.
