NBC ordered a new season of the Emmy-winning series after the cast reunited for an election year mini-episode which went viral. NBC initially ordered 10 episodes to premiere September 28. The network later increased its buy to 12 episodes, and later to 16. On August 3, NBC renewed the series for a tenth season, ordering 13 episodes.

Will & Grace, which premiered in 1998, was the first prime time network sitcom to feature a gay lead in McCormack's uptight lawyer, Will.
