Despite being one of the first series to be renewed by NBC for the 2008-2009 television season, Chuck was classified as a show "on the bubble" between renewal and cancellation in April 2009 after NBC decided to delay its decision on its renewal for a third season until early May.The show's second season did not improve on or maintain the audience numbers received in the first season and has consistently obtained low ratings, making it one of the least-watched shows in its Monday 8:00 pm ET timeslot.Concerned that the show would not be renewed for a third season, fans launched a "Save Chuck" campaign that gained momentum with the use of social-networking websites like Twitter and Facebook.
