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 the Providence, Rhode Island-based Outlet Company in 1968 (the Roths later sold the KONO radio stations to Duffy Broadcasting in 1985, KONO AM radio 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.
The Hobbys decided to liquidate their company in 1992 after an attempt to sell its entire television station group to Young Broadcasting fell through, with KCCI and WESH being the first two sold to Pulitzer, Inc. for $165 million in 1993, and KPRC-TV and KSAT-TV to The Washington Post Company on April 22, 1994.
