Today in 1988, on October 18, ABC premiered Roseanne, starring Roseanne Barr, and ushered in another of TV’s influential, significant family sitcoms. Today in 2013, starting at 10 a.m. ET, We TV presents a seven-hour marathon of its favorite Roseanne episodes. The action begins with a pair of episodes from the show’s first year – so watch for George Clooney, who was a cast member the first few seasons, playing one of the co-workers at Roseanne’s factory. ER and fame, at that point, were still six years away.
