The show was created by David Crane and Jeffrey Klarik's production company CraneKlarik in association with Warner Bros. Television.

[4] Due to the overwhelming reputation of the creators, CBS, Fox, and NBC made bids for a full 13-episode season, the latter network was also reported to have offered a 22 episode commitment, prior to seeing a pilot.

[6] Next to be cast, in January 2006, were Jason Ritter and Jesse Tyler Ferguson as Ethan Haas and Richie Velch, respectively.

Also, during the middle of 2006, it was announced that Julie Halston, Sam Harris, and David Keith had been cast in co-starring roles.

[12] As of October 9, 2006, CBS shifted the show to the 8:30 p.m. time slot, because its disappointing ratings were affecting the success of How I Met Your Mother in its second year.

[13] The pickup was conditional on the cost to CBS per episode being reduced compared to the initial episode order – this was the catalyst to Lucy Punch being fired from the show as there wasn't enough money to continue the show with eight main cast members,[14] and also saw the total staff numbers halved.

[19] On May 16, 2007, The Class was officially canceled at the CBS Upfront presentation,[20] and replaced with The Big Bang Theory.

On May 17, 2007, Jesse Tyler Ferguson posted a message on his MySpace page relating to the cancellation, as did Sam Harris, explaining that the fate of The Class was undecided until the last minute.

The campaign consisted of sending erasers, because of their connection to a school and education, and sending in printed off Moroccan Chicken recipes because of a memorable episode of The Class which saw Lina cooking Moroccan Chicken for Kat, Ethan, Benjamin, Palmer, Richie, Kyle, Duncan, and Nicole.

Seasonal rankings (based on average total viewers per episode) of The Class on CBS:[27] Note: Each U.S. network television season starts in late September and ends in late May, or occasionally early June, which coincides with the completion of May sweeps.

[35] In July 2007, The Class was nominated for the 59th Primetime Emmy Award in the category of Outstanding Art Direction for a Multi-Camera Series, the show lost to How I Met Your Mother.
