With President Barack Obama as a guest, last night’s Tonight Show With Jay Leno posted a 4.1 meter-market household rating, the highest for a Tuesday telecast since March 2, 2010, night two of Leno’s first week back as host of NBC’s late-night show. Compared with The Tonight Show‘s season-to-date average, last night’s telecast was up 52%. And that was with no help from NBC’s primetime lineup as the network averaged 2.9 million viewers in the 10 PM hour with a Prime Suspect rerun vs. 11.3 million for CBS and 9.6 million for ABC. CBS’ Late Show With David Letterman averaged a 2.7/7 household rating last night; ABC’s Nightline posted a 3.6/9, followed by Jimmy Kimmel Live! with a 1.8/6.
