Former "Saturday Night Live" castmember and "Weekend Update" anchor Seth Meyers made his hosting debut on "Late Night" Monday, stepping into fellow former "SNL"'er Jimmy Fallon as he takes over "The Tonight Show". So how were the ratings?

Meyers' first "Late Night" delivered 3.4 million viewers, and a 1.4 rating with 18-49 year-olds. He edged out Fallon's debut ratings by a half-million viewers and a tenth of a point in the demo.

Seth's guests later this week include Lena Dunham, Brad Paisley, Kelly Ripa and Patrick Stewart.
