His radio show, a mix of political and social commentary from a conservative point of view, covers legal issues in some detail, including decisions of the U.S. Supreme Court. Levin follows the traditional talk radio model of taking listener calls throughout the show.

The Mark Levin Show is a conservative talk radio show hosted by Mark Levin. The program is broadcast nationwide on Westwood One and reaches an estimated seven million weekly listeners, according to an estimate from Talkers Magazine. The Talkers estimate puts Levin’s listenership in a tie with The Glenn Beck Radio Program for fourth most-listened-to talk radio show in the United States and, counting all radio formats, tied for ninth most-listened-to radio program in the United States.
Levin began his broadcasting career as a guest on conservative talk radio programs. For many years, he was a frequent contributor of legal opinions to The Rush Limbaugh Show, where Limbaugh referred to him on-air as “F. Lee Levin,” a tongue-in-cheek reference to the defense attorney F. Lee Bailey. He was also a contributor to The Sean Hannity Show and eventually got a radio slot of his own on WABC, initially on Sundays beginning in 2002, then in the timeslot following Sean Hannity in 2003. Cumulus Media Networks began syndicating The Mark Levin Show nationally in 2006.
Hannity has nicknamed Mark Levin “The Great One”. Levin and Hannity remain frequent contributors to each other’s programs. He is a leading conservative commentator, ranked 4–6 position nationally among talk radio programs, with a minimum of 7.75 million total weekly listenership according to Talkers Magazine.
