KIIS may refer to:
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.
KIIS 1065 (official callsign 2WFM) is a commercial FM radio station in Sydney, Australia and is owned by the Australian Radio Network (ARN). The station was formerly known as 2UW, broadcasting on 1107 kHz AM, before converting to FM in 1994.
The station, now known as KIIS, began life as 2UW, commencing transmission on 13 February 1925 on 1125 kHz on the AM band. On 1 September 1935, the frequency changed to 1110 kHz and in 1978 changed again to 1107 kHz. 2UW was the home of many live radio plays and had studios for live programmes at Market Street in Sydney, near the intersection with George Street.
The management of 2UW moved the station to 365 Kent Street Sydney although for a time they retained the Market Street live audience theatre that had been used for live plays. One of its early breakfast presenters, Russ Walkington, had a character known as Gerald the Grasshopper who pre-dated Sammy Sparrow who appeared on 2UE with Gary O'Callaghan.
From the early 1960s, 2UW moved away from its older audience and actively pursued the youth market through the introduction of a Top 40 format in response to the music coming from the United States and Great Britain and to provide a vehicle for the up-and-coming Australian local rock scene.
