Weekday mornings begin with The John Boy and Billy Show syndicated by Premiere Networks from WRFX Charlotte.

It is a guy-wired aerial mast, designed for broadcasting Channel 10 WBIR-TV, originally the CBS Network affiliate for Knoxville (geographical coordinates: 36°8′6″N 83°43′29″W / 36.13500°N 83.72472°W / 36.13500; -83.72472).

While the tower was on one of the tallest peaks in the area, WBIR-TV's signal was shielded by mountains from some communities west of Knoxville, including Farragut, Oak Ridge, and Lenoir City.

To improve its signal in those towns, Channel 10 relocated to Sharp's Ridge near downtown Knoxville during the 1970s, and the FM station remained on the original tower.

Before the tall WBIR-TV mast was built in 1963, the owner of the television station had planned the tower to be erected on nearby House Mountain, the tallest point in Knox County, Tennessee.

WBIR-AM-FM were network affiliates of ABC, carrying its dramas, comedies, news and sports during the "Golden Age of Radio."

As network programming moved to television, WBIR-AM-FM switched to a full service, middle of the road format of popular adult music, news, talk and sports.

At the start of 1983, WIMZ altered its format to add more current new wave and heavy metal music acts and reduce much of the 1960s and early 70s classic rock.

During the 1980s and 1990s, WIMZ-FM had a popular morning program hosted by Phil Williams, Billy Kidd, and Colvin Idol (later replaced by David Henley).
