While ratings for Colbert's show have declined over the last decade, the program has consistently achieved the highest views of any show in the 11:35 p.m. hour, outdrawing ABC's "Jimmy Kimmel Live" and NBC's "The Tonight Show Starring Jimmy Fallon," according to Nielsen.

A review by Fox News Digital found that left-wing journalists and other media figures made hundreds of appearances on "The Late Show with Stephen Colbert."
