Big changes are coming to NBC next fall, including a radical remaking of its Thursday night lineup. As part of a new fall schedule just announced, the Peacock network will shift Parks and Recreation to the 8 p.m. lead-off slot Thursday, delay the return of Community, add three new sitcoms (including The Michael J. Fox Show) and relocate Parenthood to the 10 p.m. timeslot which once housed E.R. and L.A. Law. In another big move, Revolution will give up its cushy slot following The Voice and air Wednesdays at 8, with the buzzy James Spader drama The Blacklist inheriting the 10 p.m. Monday slot. Overall, NBC is changing at least one hour every night of the week (except Sundays in the fall, which will remain devoted to football), with a new show (or newly relocated show) airing at 10 p.m. every weeknight. NBC is also saving some big guns until later in the season, hoping to use the Winter Olympics to launch the J.J. Abrams-produced Believe, new Tuesday comedies About a Boy and The Family Guide and the Gillian Anderson-Dermot Mulroney thriller Crisis. And it’s also delayed decisions on renewals for Hannibal and The Celebrity Apprentice (sorry, Donald!) Vulture will have further analysis later, but check out the full NBC fall and winter schedules below.
