CBS has renewed the comedy show 'Mom' which stars Anna Faris and Oscar-winner Allison Janney for a sixth season. Kelly Kahl, president of CBS Entertainment said of the renewal Monday, "Mom has been a lynchpin comedy for us over the last several years. It?s a fearless series that tackles provocative social issues with laughter and grace, and a large, loyal audience has followed." The show, which premiered back in the fall of 2013, is averaging over 11 million viewers during its current season.
