The fans have won against the evils of big-shot networks, since NBC has conceded and renewed the series Chuck for a third season. Despite low ratings, the Josh Schwartz action-comedy was given another shot and will be returning next fall.

Chuck's new installment will compose of 13 episodes, as NBC picked it up once more from Warner Bros. Still, good news is usually accompanied by its counterpart. It has been reported that the company made some budget concessions to secure the show's return. This means the season might not be as, well, "complete" as its predecessors.
According to Entertainment Weekly's Michael Ausiello, "The 13-episode pickup came after Warner Bros. agreed to make significant budget concessions, including scaling back the number of episodes several members of the show's stellar supporting cast will appear in and, per one insider, possibly eliminating one actor altogether (R.I.P. Anna Wu?). The show is also expected to cut two of its staff writers."
