When it comes to the popular CBS comedy The Big Bang Theory, there are a few things that come to mind: the nerdy main characters, the laugh track, the endless puns, and the two pilots.

But why did the show have two pilots?

The Big Bang Theory was created by Chuck Lorre and Bill Prady, and developed by them and Steven Molaro.

The series first aired on CBS on September 24, 2007 and has since become one of the most popular shows on television.

The original pilot of The Big Bang Theory was shot in 2006 and featured a different cast.

While the show was initially created with the four main characters in mind, the original pilot didn't quite capture the essence of the characters and the show's appeal.

The pilot was deemed unsatisfactory, and the network made the decision to shoot a second pilot.

The second pilot featured a much better cast, with Johnny Galecki and Jim Parsons playing Leonard Hofstadter and Sheldon Cooper respectively.

The second pilot also featured Kaley Cuoco as Penny and Simon Helberg as Howard Wolowitz.

This cast was better able to capture the essence of the show and the characters, and the network decided to move forward with the show.

The Big Bang Theory has since become one of the most successful sitcoms on television, with 12 seasons and 276 episodes. The show has received numerous accolades, including 10 Emmy Awards.

It has also spawned a spin-off prequel series, Young Sheldon.

The network's decision to shoot a second pilot was a wise move, as it allowed the show to properly capture the essence of the characters and the show's appeal.

The original pilot didn't quite capture that, and the network was smart to go back and shoot another pilot.

This allowed the show to have the success it has enjoyed for so many years. In short, The Big Bang Theory had two pilots because the original pilot did not properly capture the essence of the characters and the show's appeal.

The network was smart to go back and shoot a second pilot, which featured a better cast and was able to capture the show's appeal. This allowed the show to become one of the most successful sitcoms on television.
