President-Barack-Obama-David-Letterman-The-Late-Show-CBS.jpgPresident Barack Obama’s appearance on “The Late Show with David Letterman” boosted the CBS talk show to its highest overnight ratings since February 2010.

Last night’s “Late Show” averaged a 4.0/10, topping all hours since the Feb. 9, 2010 installment with Jennifer Garner, swimsuit model Brooklyn Decker and Sade delivered a 4.3/10. That was during the transition period after Conan O’Brien had left “The Tonight Show,” but before Jay Leno resumed hosting.

The Obama ratings are up 60% from Letterman’s Tuesday average this year and up 67% over the show’ weekday average during the 2011-2012 season.

Obama’s appearance was particularly powerful in New York, attracting nearly half a million viewers and a 2.6 rating in adults 25-54. It was the most watched “Late Show” in New York since Jan. 2, 2008. CBS notes “Late Show” was also tops in the time period among total viewers in Los Angeles, Chicago, Philadelphia, San Francisco, Boston, Minneapolis, Sacramento, Pittsburgh and Baltimore.

The ratings surge also helped lead-out “The Late Late Show with Craig Ferguson” to its highest ratings since Feb. 9, 2010.
