NBC spreads out its fall premieres

Joelmchale_community_290 NBC had already announced that "The Jay Leno Show" would premiere a week before the official start of the 2009-10 TV season. The network will take its time rolling out the rest of the fall schedule, though.

Leno's prime-time show will premiere Monday, Sept. 14 and run every weeknight at 10 ET. Two other nights of programming -- "The Biggest Loser" on Tuesdays and the Thursday comedy block -- will also debut that week, while the Monday, Wednesday and Friday shows will join them the week of Sept. 21, when Nielsen starts counting ratings for 2009-10.

The Thursday schedule will include, for three weeks, another round of "Saturday Night Live Weekend Update Thursday" at 8 p.m., followed by "Parks and Recreation," "The Office" and newcomer "Community." The latter show will shift to 8 o'clock on Oct. 8 to make room for an hour-long "Office." Emmy winner "30 Rock" will join the party late again, debuting its fourth season on Oct. 15.

Also of note: "Heroes" will have a two-hour premiere on Monday, Sept. 21, which will push the debut of "Trauma" to Sept. 28. "Saturday Night Live" will kick off its season on Sept. 26.
