CBS has officially pulled the plug on new Carsey-Werner Co. sitcom “Frannie’s Turn,” which joins “Angel Street” as a casualty of the web’s Saturday lineup.“Frannie,” which stars Miriam Margolyes, had averaged a 6.2 rating, 12 share in Nielsen for four airings at 8 p.m. Saturday, leading into sophomore series “Brooklyn Bridge.” CBS remains committed to that Gary David Goldberg half-hour and will likely move the show up to 8 p.m. followed by movies during the November sweeps. No scheduling has been announced, but a likely long-term candidate for the Saturday lineup would be “How’d They Do That,” a reality series from Lorimar TV. Columbia Pictures TV’s “Raven,” a late addition to the fall Saturday lineup, remains in production and will return to the schedule even if it’s yanked for sweeps. NBC has pulled the plug on three new series on its Friday lineup, meaning five of the season’s 33 new shows have already met the scheduling axe. ABC and Fox Broadcasting Co. have yet to cancel any of their new shows. CBS reportedly was skeptical about prospects for “Frannie” coming into the season but wanted to be in business with its producer, Carsey-Werner.
