KIOZ, also known as Rock 105.3, is an active rock station in San Diego, California. It is licensed in San Diego, California, and is owned by iHeartMedia, Inc.. The station's studios are located in San Diego's Serra Mesa neighborhood on the northeast side, and the transmitter is located in La Jolla.
105.3 was licensed in 1954 and started off as KITT, a beautiful music station. The transmitter was downtown on the Bank of America building. The station struggled financially for many years, the station was perpetually for sale, at one point for as low as $100,000.00. In the early 80's KITT was bought by KCBQ and turned into a simulcast of 1170. KCBQ-FM 105.3 changed formats many times. KCBQ-FM signed on as "KCBQ Country" to compete with KSON, that failed and it switched to "The Eagle", the Eagle flopped, and KCBQ became an oldies station (which did well). KCBQ then hired back former program director Rich Brother Robbin, Rich changed the format to "Modern Oldies", it was at this point that Compass Media (owner of KCBQ AM/FM) sold the stations to Par Broadcasting.
