Photos: It's Official: Stephen Colbert replaces Dave Letterman on 'The Late Show'

Although David Letterman's replacement wasn't expected to be named so soon, a mere week after Dave's surprise retirement announcement CBS has gone ahead and chosen his successor: Stephen Colbert, who'll take over as new host of The Late Show when Dave retires next year.

According to this morning's unexpected network announcement, the Colbert Report host has been officially named new Late Show host, with the date of his first day on the job to be announced after Dave "determines a timetable for his final broadcasts in 2015."

In addition, "specific creative elements, as well as the producers and the location for the Colbert-hosted Late Show, will be determined and announced at a later date." At this point, it's still up in the air whether the show will remain in New York and continue to broadcast from the Ed Sullivan Theater, or potentially move to Los Angeles.

#Wow, nice one, congrats Colbert!!!
