UPDATE: Leno Numbers Even Bigger, Boost Conan

O'Brien's “Tonight Show” gets best local market showing since June.

Final Nielsen numbers show Jay Leno did even better than reported this morning — and he boosted Conan O'Brien, too.

 

Leno ended up attracting 18.4 million viewers Monday (up from 17.7 million) and a 5.3/14 in adults 18-49 (up from a 5.1).

 

Meanwhile, the Leno halo gave O'Brien's "The Tonight" show a 1.4 rating among adults 18-49 in 24 metered markets. That's up from O'Brien's 0.9 average demo rating last week, and his best performance in the demo since June 26.
