Fox Broadcasting Co. will yank the new Viacom drama “Key West” and replace it with the Robert De Niro-produced anthology series “Tribeca” as of March 23.The show, which features Philip Bosco and Joe Morton as its sole recurring characters, will air at 9 p.m. (following “Class of ’96”) in an effort to bolster the weblet’s struggling new Tuesday lineup. Fox has ordered seven episodes of the series, which is exec produced by David J. Burke, De Niro and Jane Rosenthal in association with TriStar TV. “Key West” has averaged a 4.7 rating, 7 share in Nielsen for its first six airings, slightly worse than its lead-in “Class,” which — as a vote of confidence — had its episode order expanded before its premiere. Separately, ABC has changed its mind about some previously announced scheduling changes, placing “Dinosaurs” on hiatus instead of moving it to Sundays and saving what might be the final seg of “Life Goes On” until later this season. The network will now place “Dinosaurs” on hiatus after tomorrow (when it steps aside for new Friday sitcoms) and pair “America’s Funniest Home Videos” in the 7 p.m. hour Sunday with usual running mate “America’s Funniest People,” starting March 14. News magazine “Day One” will go into the 8 o’clock hour previously occupied by the video shows. “Life Goes On” will get an additional airing March 7 in its Sunday slot, with its last episode to air later in the year. ABC previously announced those two installments of the Warner Bros. TV series would play on consecutive Saturdays starting March 20. ABC said “Dinosaurs” will return with original episodes in May. The Disney-Henson Prods. comedy has been a steady if unspectacular performer since moving into the Friday lineup at 9 p.m. last season.
