David Letterman has just signed a deal that will keep him on latenight on CBS for four more years through the 2009-2010 season. Daves competition at that hour Jay Leno is leaving in 2009 when Conan o Brien will take over the Tonight Show. The new deal was a little bit surprising considering he had heart surgery in 2000 and was also kept of the air for shingles in 2003, so it was thought he might want to walk away. Dave is one of the highest paid people on television and even though Jay Leno has higher ratings im sure he will do okay in his new deal. His show is very entertaining and im glad to see it will continue for several more years.
