David Letterman Signs Off With 10Year Ratings High
David Letterman signed off on Wednesday night, putting the finishing touch on a 33-year career in late-night  the last 22 of which he's spent at CBS. Capping off several weeks of ratings spikes and two nights of five-year highs, the telecast was obviously up. The star-filled goodbye averaged a 9.3 local rating, hitting its highest score since December 2005. That telecast brought a visit from friend Oprah Winfrey, who hadn't visited Letterman since 1989., Full ratings for the telecast will be available later on Thursday, but as it stands, the 1130 p.m. Late Show outrated all primetime telecasts for the night. One fellow benefiting a great deal from all of this is James Corden. The new Late Late Show host has been hitting series highs for his brief tenure, rising last night to a 2.5 overnight rating.
