WTTW plans to make big changes to its signature news magazine in January when former news anchor and CBS News correspondent Carol Marin signs on at Chicago Tonight. Marin's hiring, announced Oct. 20, foreshadows the exit of current anchor Bob Sirott, reports the Chicago Sun-Times. "The whole show will be changing," a WTTW spokeswoman tells Crain's Chicago Business.
