The station signed on in August 2000; 24 years ago (2000-08). It was known as WBZM, 107.7 The Buzz. WBZM was owned by Cromwell Broadcasting, and was operated out of the company's Peoria cluster. It had an Alternative Rock format, with the syndicated "Bob and Tom Show" in the morning. The disc jockeys were all the same as on 99X, which was, at the time, WIXO on its original Bartonville frequency of 99.9.
When Cromwell sold the Peoria cluster in 2001, WBZM was not included in the sale. Operations were moved to Cromwell's Decatur cluster and WBZM quickly went on the sale block. At the end of 2001, AAA Entertainment purchased the signal and began simulcasting 96.7 WIHN Normal, then later 99.5 WDQZ Lexington.
On March 28, 2003, AAA debuted WYST, an AC station branded as "Star 107.7". In June 2003 the station's signal was upgraded and moved from Fairbury to Lexington, Illinois.[clarification needed]
In February 2007, the format was modified to R&B/Soul with the slogan "The Heart and Soul of the Twin Cities", which had more of a rhythmic lean than competitor 100.7 WVMG.
In April 2007 the station began a local marketing agreement (LMA) with Great Plains Media. No immediate format change was made.
On June 29, 2007, at Noon, just several days after the closing the sale on WYST, Great Plains Media flipped the format to Country as "107.7 The Bull." The station is the first[citation needed] to take on heritage WBWN in the Bloomington market. On August 17, 2010, WYST changed its call letters to WIBL to go with the "Bull" branding.
