WTTV originally signed on the air on November 11, 1949, as an NBC affiliate on VHF channel 10, which later moved to channel 4 on February 21, 1954 and switched affiliations to ABC in 1956.
Although WTTV was Indianapolis' strongest independent station at the time, the station declined an offer to affiliate with the upstart Fox network, which later opted for WXIN on October 9, 1986.
