air, Channel 6 KOIN-TV. Because KOIN Radio was a CBS Radio affiliate, KOIN-TV carried CBS TV shows. 1950s–1980s In the 1950s, as network programming moved from radio to television, KOIN began airing a full service middle-of-the-road format. On May 12, 1977 the call letters changed to KYTE featuring a Top 40 hits format. On September 4, 1979, it switched to country music as "97 Country." In 1981, the station flipped to automated "Music of Your Life" adult standards programming. On January 27, 1989, KYTE began playing classical music, picking up that format when 101.1 KYTE-FM dropped classical for smooth jazz as KKCY "The City." The classical format turned out to be short-lived on AM 970. 1990s In 1990, the station changed call letters to KESI and aired a mostly instrumental easy listening format branded as "Easy 970." On May 1, 1991, the station again changed call letters to KBBT and began stunting. 18 days later, the station began airing an alternative rock format known as "970 The Beat." In July 1996, KBBT began simulcasting on KDBX 107.5 FM (now KXJM), and tweaked its format to Modern AC.

KUPL switched to oldies as "Cruisin' Oldies 970" on January 23, 2001. 2000s On August 1, 2001, KUPL changed call letters to KUFO, and on August 7, switched to a new hot talk format, branded as "Extreme Talk 970." Hosts featured on "Extreme Radio" include Bob Rivers, Don & Mike, Opie & Anthony, The Sports Junkies and Ron & Fez. On October 11, 2002, after a brief simulcast with active rock KUFO-FM, 970 changed its call letters back to KUPL, returning to classic country as "Straight Country 970." AM 970 continued as KUPL until February 2, 2005. At that point, it became KCMD, letters chosen to reflect its "all-comedy format." That same year, after MAX 910 abandoned its hot talk format, CBS Radio (formerly Infinity Broadcasting before December 2005), hoping to enlarge the station's audience, decided to broadcast syndicated programming, including The Tom Leykis Show, Phil Hendrie, and Don and Mike, shows that had previously
