NBC ANNOUNCES SEASON FINALES FOR SPRING 2011

In Addition, "30 Rock" Celebrates 100th Episode with Special One-hour Edition on Thursday, April 21

UNIVERSAL CITY, Calif. - March 8, 2011 - NBC today announced many of its season finales for such series as "30 Rock," "The Office," "Parenthood," "Parks and Recreation," "Community," "The Biggest Loser" and "The Event," among others.

In addition, NBC's Emmy Award-winning comedy "30 Rock" (Thursdays, 10-10:30 p.m. ET) celebrates its 100th episode with a special one-hour edition on Thursday, April 21 (10-11 p.m. ET). "30 Rock" celebrates its 100th episode as "TGS," the show-within-the-show, faces the prospect that its 100th episode may be its last. A new corporate boss, a star in hiding, and a mind-altering gas leak may doom America's fourth-favorite Friday night sketch comedy show.

Storyline details for each series finale will be announced later.
