NEW YORK (CNNMoney) — The new battle for late night is officially underway.
After beating out Jimmy Fallon with a big opening night, viewership for Stephen Colbert’s second installment of the Late Show dipped to 3.7 million. That put him behind Fallon’s Tonight Show, which won the night with an average of 4.1 million viewers.
Fallon also beat Colbert in the the prized advertising demographic of people aged 18 to 49 with 1.6 million viewers compared to Colbert’s 972,000.
To be fair, a decline was somewhat expected, given that Colbert’s opening night was a must-watch TV event that was heavily promoted by CBS.
Much of Fallon’s success was arguably thanks to his old friend, Justin Timberlake, who appeared on the show to take part in the duo’s sixth installment of the “History of Rap.”
The bit, where Fallon and Timberlake sing — in rapid succession — a medley of rap songs, is one of the most popular in late night TV. It’s also a viral hit for the Tonight Show, with more than 550,000 YouTube views since the sketch aired at 11:35 p.m. last night.
