In 1953, KFSD-TV (now KGTV, and not directly related to today's KFSD) became the second TV station to sign on the air in San Diego, at channel 10 on the VHF band. In 1961, 600 KFSD was changing formats, so it was decided to change the call letters. The owners at the time fed facts about San Diego and its people into a new device called a computer, which was then asked to give them the perfect call letters for the station. The computer gave them the call letters KOGO. Thus, in 1961 the legendary San Diego station known as KOGO was born.
