KSAT 12 hasn't always been called KSAT. In fact, the station went on the air as KONO TV in February 1957, with the inauguration of President Eisenhower.

In 1968, the station was purchased by the Outlet Co. of Providence, R.I. It officially became KSAT 12 in 1969, when the company changed its call letters.

Since then, KSAT has had several owners. The Rockefeller Group purchased KSAT 12 in 1984. H&C Communications, a Texas-based company, purchased KSAT 12 in 1986. Post-Newsweek, the current owners of KSAT 12, bought the station in April 1994.
