Colbert reaches a new late-night milestone

Nielsens

NEW YORK — Stephen Colbert hit another milestone in his stunning late-night turnaround against Jimmy Fallon of NBC’s “Tonight” show.

Colbert won in the Nielsen company’s ratings for the ninth consecutive time last week, his margin of 400,000 viewers the widest lead since the CBS star overtook Fallon with a sharp concentration on politics. Fallon aired a rerun Friday; otherwise the shows were all fresh last week. More ominously for NBC, Colbert tied Fallon among viewers aged 25-to-54 for the first time, encroaching on younger viewers who are more valuable to advertisers.

Fallon had been the unquestioned late-night king until the advent of the Trump administration, and he’s been struggling to regain his footing.

Boosted by the NCAA tournament, CBS dominated last week with an average of 9.7 million viewers in prime time. NBC had 5.3 million, ABC had 4.4 million, and Fox had 2.7 million.
