A year and a half after it began, Stephen Colbert’s late-night resurgence shows no signs of letting up. Halfway through the 2017-18 season, The Late Show With Stephen Colbert is up 30 percent in total viewers from a year ago (3.83 million, over 1 million more than The Tonight Show Starring Jimmy Fallon’s 2.79 million audience). And while Fallon is still ahead in the 18-49 demo, his lead has shrunk to just one tenth of a ratings point (0.7 to Colbert’s 0.6).
