Subject to multiple format changes throughout the 1990s, 2000s and early 2010s, and garnering a Guinness World Record for playing Take Me Out to the Ball Game continuously as a stunt in 1994, WJMP ceased operations after the license was turned in to the Federal Communications Commission (FCC) for cancellation.
For its entire existence, the station operated at a transmitter site in Franklin Township with a maximum power output of 1,000 watts, using a six-tower, daytime-only directional antenna pattern.
[3][4] Howie Chizek began his long career with WKNT and its FM successor on June 3, 1974, after previous stops at WBBW in Youngstown and at Ohio University's student-run radio station.
[5] Programming on the two stations was split on August 4, 1980, when WKNT-FM became WNIR, maintaining the hybrid contemporary music/talk format, while WKNT converted to country music with Steve Cherry in mornings and Jerry Lee Goddard in afternoons.
[8] After years of declining ratings, two of WKNT's three announcers were fired in early September 1988, but management claimed the station would continue with the country format.
[14] When the 1994 Major League Baseball season ended prematurely due to labor unrest on August 12, 1994, WJMP engaged in stunting by playing two different versions of Take Me Out to the Ball Game, in a continuous loop, from sunrise to sunset.
