Jimmy Fallon's first Tonight Show brought in 11.3 million viewers. It's not as high as Jay Leno's 14.6 million-strong sendoff, but given the late hour and smaller Olympics lead-in, it's a strong sampling. Fast Official ratings for Monday also lift Fallon's overnights in the key demo. The host averaged a 3.8 rating among adults 18-49, putting him on par with Conan O'Brien's 2009 Tonight debut. Among total viewers, Fallon came in just shy of O'Brien's 11.9 million.
