David Letterman’s appearance on Jimmy Kimmel Live last night delivered the ABC late-night show its biggest Wednesday audience since its 2003 debut. A total of 2.35 million viewers watched Letterman’s first visit to Kimmel. The second-best Wednesday for Kimmel came on January 4, 2006, just after ABC’s broadcast of the Rose Bowl, when 2.305 million viewers tuned in.
Broadcasting from Brooklyn, Kimmel also marked its best Wednesday rating in the adults 18-49 demographic since October 24, 2007, with 985,000 tuning in. That was the best the show has done on any night in the demo since June 19, 2012, during the NBA Finals. Although scheduled to broadcast from NYC all week, Kimmel shut down Monday due to Hurricane Sandy. The show resumed Tuesday.
