The station first signed on the air on October 11, 1971; originally operating as an independent station (though it ran ABC, NBC, and CBS shows that the local affiliates passed on at times as well), it was the first television station founded by the Pappas brothers, Mike, Pete and Harry, through their company, Pappas Television. The brothers already owned radio stations KGEN (1370 AM) and KBOS (94.9 FM) in Tulare, KMPH's original city of license. The station's original studios were located on Mooney Boulevard in Visalia. The funding for KMPH came from general manager Harry Pappas' plan of having hundreds of investors each investing a small amount of money that was needed to construct the station, rather than having one investor providing all the capital; as a result, the Pappas brothers had a combined ownership stake of only 30.5%, with the other 69.5% controlled by other investors.
