He was a frequent caller on the Sportslineradio show on WTAMAM 1100,. The show was hosted by the acerbic Pete Franklin and dealt with Cleveland sports. Franklin, who would typically cut off most callers, began giving "Mike from Mayfield" some latitude due to knowledgeable commentary, particularly regarding the Cleveland Browns. Franklin began mockingly referring to Trivisonno as "Mr. Know It All," a moniker he would carry into his own radio career. Trivisonno eventually began his own broadcasting career in 1987, working for a time at WNCX, commenting on sports and becoming a full-time personality from 1989–1992. He began hosting Sportsline on WWWE in 1994. At first, the show aired from 6-11 p.m. The show did well in the ratings, even though it was usually up against Cleveland Indians games on WKNR. It did so well, the decision was made to put Trivisonno in afternoon drive-time ultimately leavingSportsline to other hosts. Since then, The Mike Trivisonno Show is usually either first or second in ratings for his time slot in the market. His show had been originally dedicated mostly to sports, but over time it has become a forum for discussing sports, politics, local issues, current events, or whatever else is on Trivisonno's mind at the time. He discusses topics with listeners who call in to the show and/or with his various producers and sidekicks that work alongside him. Trivisonno's popularity and high ratings have led him to be ranked numerous times among Talkers Magazine's "Heavy Hundred", including most recently in 2015, when he came in at #72. He was also a nominee for the Large Market Personality of the YearMarconi Award in 2010.
