The station first signed on the air on May 14, 1948 as WBEN-TV. It was Buffalo's first television station, the fifth-oldest station in New York state, and the 24th in the United States. The station was originally owned by the Butler family, along with the Buffalo Evening News and WBEN radio (930 AM and 106.5 FM, now WTSS at 102.5); the holding company for the WBEN stations was WBEN, Inc. Its radio sister had been one of CBS Radio's first 16 affiliates when that network premiered in 1928, but by that point had switched networks to NBC Blue. Accordingly, channel 4 originally signed on as an NBC affiliate. WBEN-TV picked up CBS programming in January 1949, and has remained with that network ever since.
As the only station in Buffalo for its first several years, channel 4 also carried secondary affiliations with ABC and DuMont. It lost NBC when WGR-TV (channel 2, now WGRZ) signed on in August 1954, and ABC to WGR-TV when NBC moved its programs to newly purchased WBUF-TV (channel 17) in 1956. WBEN-TV continued to share DuMont programming with WGR-TV until 1956 when that network ceased operations. WBUF-TV gone dark in 1958, two months before the sign-on of present-day ABC affiliate WKBW-TV (channel 7).
