The Early Show, CBS' ratings-challenged morning program, just got a wake-up call in the form of a major anchor shake-up.

Harry, Maggie, and Dave will all be gone soon. Starting January 3, Erica Hill and Chris Wragge will be the new co-anchors of the struggling morning program, which has lagged behind NBC's powerhouse The Today Show and ABC's Good Morning America for years. In addition to Hill and Wragge, Jeff Glor will serve as The Early Show's news reader and Marysol Castro, formerly of GMA's weekend show, will join the team as the main weather anchor.

Sean McManus, president of CBS News and Sports made the official announcement Tuesday.
