KBET, 850AM, was a commercial radio station in Thousand Oaks, California, United States.
It began as KGOE, which had an adult standards format. In addition, it carried games of the University of Oklahoma's football team as possibly the most distant affiliate of the Sooner Radio Network.
In 1984, it changed call signs to KMDY and adopted a format which included stand-up comedy and comedic albums. This format lasted until 1992, when it joined the all-children's network known as "Radio AAHS" and simulcast KPLS. When Radio AAHS went off the air, the station, which by this time had become KAHS, switched to adult standards as KLYF, then a few months later all-sports, once simulcasting KXTA, "Xtra Sports 1150." About this time it was purchased by Clear Channel Communications.
Later it became general talk station KBET, then KACD, picking up the "World Class Rock" format abandoned by 103.1FM. The station then became "KIIS-AM" (under the call letters KBET, simulcasting KIIS-FM), then KBET again. In 2003, it simulcast classic country station KTDD in San Bernardino.
In 2004, 850 AM became a simulcast of KIIS-FM again. Sometime after 2005, the lease on the land of the towers' location ran out and could not be renewed. The towers were then demolished and a housing tract was built on the former tower location. The frequency is now silent. Meanwhile, the KBET call letters are now attached to a station in Winchester, Nevada.
