When The Rosie O'Donnell Show premiered in 1996, host Rosie O'Donnell was dubbed "The Queen of Nice" for her sugary personality in the midst of a world of sour, dour daytime TV. Known for its light-heartedness and featuring of Broadway production numbers, the show was a hit with the at-home-mom crowd, and Rosie became one of the most-loved ladies of the boob tube before calling it quits to be a full-time mama.
