David Letterman has reached an agreement with ABC that will keep the late-night host around for four more years. His contract extension keeps Dave on the Late Show through the 2009-2010 season. Interestingly enough, this is one year past the plan for Leno to step down from the Tonight Show and pass the torch to Conan O’Brien. According to Nielsen Media Research, Leno continues to be the ratings winner, averaging 5.71 million viewers nightly, versus 4.16 million per night for Letterman. The rivalry has been ongoing since Leno took over Johnny Carson’s post on the Tonight Show—and it looks like the competition will now continue against O’Brien. CBS Entertainment and Letterman spokespeople had no comment about the negotiations since the deal is not official yet. Even after all these years, I still prefer Letterman to Leno—Leno is more corny than anything, but Letterman’s goofy persona wins me over. Goofy beats corny in my book any day, but what to do when Letterman and O’Brien go head to head? Two goofs—don’t make me choose!
