The station first signed on the air on January 21, 1957, as KONO-TV; it was founded by the Mission Telecasting Corporation (no relation to today's Mission Broadcasting, a partner company of Nexstar Media Group), which was owned by the Roth family, owners of KONO radio (860 AM and 92.9 FM).
The Roths sold channel 12 to Providence, Rhode Island-based The Outlet Company in 1968 (the Roths later sold the KONO radio stations to Duffy Broadcasting in 1985, KONO (AM) is now owned by Cox Radio while KONO-FM is now KROM, under the ownership of Uforia Audio Network); the following year, in 1969, the station changed its call letters to KSAT-TV (in reference to the station's city of license)
Outlet was taken private in 1986 and the company's new owners sold KSAT to Houston-based H&C Communications, which owns NBC-affiliated flagship station KPRC-TV.
