Series overview

Production history

The show was first developed for the 2006-2007 television season. At that time, it was very different from the show that was later broadcast. Only Jim Parsons & Johnny Galecki were part of the original pilot. The character now played by Kaley Cuoco was much meaner to the geeks. CBS did not pick the show up, but gave Bill Prady and Chuck Lorre a second chance. They brought in Kaley Cuoco, Simon Helberg and Kunal Nayyar. They retooled the show.

The second pilot of The Big Bang Theory was directed by award-winning television directing veteran James Burrows. He decided not to stay with the show. This reworked pilot led to a 13-episode order by CBS on May 14, 2007. Before its airing on CBS, the pilot episode was distributed on iTunes free of charge. The show premiered September 24, 2007. It was picked up for a full 22-episode season order on October 19, 2007.

Production on the show was halted on November 6, 2007 by the 2007–2008 Writers Guild of America strike. When the strike ended, the show was picked up for a second season for the 2008-2009 television season.

The show returned on March 17, 2008 . It had an earlier time slot and nine new episodes. The second season premiered, in the same slot, on September 22, 2008. During that season, the show's ratings grew. That led to a two-year renewal through the 2010-11 season.

David Saltzberg, a professor of physics and astronomy at the University of California, Los Angeles, checks scripts and provides dialogue, math equations and diagrams used as props. He says he is more consultant than contributor. Executive producer/co-creator Bill Prady said, "In fact, we're working on giving Sheldon an actual problem that he's going to be working on throughout the [first] season so there's actual progress to the boards ... We worked hard to get all the science right."

Theme song

Barenaked Ladies wrote and recorded the theme song, which describes developments the universe has undergone since the dawn of time. On October 9, 2007, a full-length (1 minute and 45 second) version of the song was released.

DVD/Blu-ray releases

• Despite the third and fourth seasons receiving Blu-ray releases with their DVD releases, the first and second seasons were only available on DVD when they were released. Warner Bros. has then released the first two seasons on Blu-ray/DVD combo packs with UltraViolet downloads on July 10, 2012. All of the episodes from seasons 1 & 2 on Blu-ray received newly edited surround-sound audio, with the first season including a never-before-seen gag reel, which was not included during the initial first season DVD release.
