Despite its ratings challenges, NBC renewed five of its dramas for next season.
Among the returning shows are the sci-fi adventure series "Revolution" from J.J. Abrams and Eric Kripke; the fantasy series "Grimm," the family drama "Parenthood," the first-season breakout hit "Chicago Fire" and the long-running "Law & Order: SVU."
Of the returning shows, "Revolution" and "Chicago Fire" are the newest, getting second seasons after performing relatively well in the ratings. "Revolution" was one of the season's first big hits, with a premiere audience of about 24.2 million having watched all or part of it. It has since settled to a regular audience of about 11 million each week, making it one of the top-rated network dramas.
"Chicago Fire" had a quieter debut but it has steadily grown its audience, and NBC has announced plans to develop a spinoff about Chicago's police department.
