KTOK and its sister stations, KGHM, KJYO, KOKQ, KTST and KXXY-FM, have offices and state of the art studios at 6525 North Meridian Avenue on the Northwest side of Oklahoma City.

Because AM 1000 is a clear channel frequency reserved for Class A WMVP in Chicago, KNWN in Seattle and XEOY in Mexico City, KTOK's nighttime signal must protect those stations.

The rest of the weekday schedule is made up of nationally syndicated conservative talk shows, mostly from co-owned Premiere Networks.

By the 1950s, as network programming was moving from radio to television, KTOK switched to a full service, middle of the road (MOR) format of popular adult music, news and sports.

As WKY and KOMA became youth-oriented Top 40 stations, KTOK began carrying sports from their former networks, NBC and CBS, including the World Series, championship fights and auto racing.

But it had to use a complicated directional antenna system to make the higher nighttime power work, while still protecting other stations on AM 1000.

In 1978, KTOK was acquired by the Insilco Broadcasting Group, which also bought an FM station at 102.7, KZUE, which aired an adult contemporary music format.

KTOK and its FM station were acquired in 1992 by San Antonio-based Clear Channel Communications (the forerunner to current owner iHeartMedia).

In early 2022, iHeartMedia Oklahoma City moved KTOK, along with sister stations KGHM, KJYO, KTST, KXXY-FM, KREF-FM (now KOKQ), to new state of the art studios at 6525 North Meridian Avenue.
