Stromberg-Carlson merged with General Dynamics in 1955. General Dynamics was not interested in owning broadcast outlets, and put the WHAM radio and television outlets on the market. In 1956, WHAM-TV was sold to Transcontinent Broadcasting, which owned WGR radio and WGR-TV in Buffalo; the new owners changed the call letters to the current WROC-TV. In 1961, Transcontinent sold the station to Veterans Broadcasting Company, which subsequently sold its half of what is today WHEC-TV (channel 10) to the Gannett Company, then based in Rochester. The acquisition by Veterans Broadcasting also gave WROC-TV new sister stations on radio, as WVET-AM-FM (1280 AM and 97.9 FM) changed their call signs to WROC (AM) and WROC-FM. (The WHAM-TV callsign is now used on Rochester's ABC affiliate, channel 13, previously known as WOKR. Other than the shared callsign, that station is unrelated to the earlier WHAM-TV.)
