NBC is keeping the lights on for Friday Night Lights.
The acclaimed series has been renewed for two more 13-episode runs and will air through the 2010-11 season, the network said Monday.
"Not only do we know the show is staying on, but we know exactly how many episodes we are going to do," said executive producer Jason Katims. "We'll be able to think about where we might want to lead to ... what kind of stories we want to tell."
The Texas football-and-family drama starring Kyle Chandler and Connie Britton has struggled in the ratings but has been a critical bright spot for NBC, drawing consistently good reviews and Emmy and Peabody nominations and awards.
NBC is glad to stand behind a high-quality show with "a tremendously loyal fan base," said Angela Bromstad, president of prime-time entertainment for NBC and Universal Media Studios.
