The Big Bang Theory is a comedy TV series which is currently aired on the CBS channel in the US. Two young physicists, Sheldon Cooper and Leonard Hofstadter, along with their friends, are in the middle of the story. The title of the show is based on a widely accepted theory of the Universe’s formation, according to which the so-called Big Bang initiated everything we deal with, by expanding hot and dense matter from a single point to the current size. The matter has been continuously expanding ever since having created the familiar Universe.

The show premiered on the TV screens on September 24, 2007. In spring 2014, creators have announced that 3 more seasons are to follow, which was the fans’ biggest joy at the time. So, apart from the season 9, the viewers will also see season 10. The new episodes will be out in 2015.

Interesting Facts

The actors' dialogs, as well as various schemes and equations, are carefully checked by a physics and astronomy professor of California University, which helps avoiding crucial mistakes that can be made in films and TV shows.

The main theme song was created by a Canadian rock band Barenaked Ladies. Writing of a song commemorating the birth of the Universe was inspired by reading a Simon Singh book titled Big Bang.

In Belarus, The Theorists series was put into production. Its idea and plot are completely based on The Big Bang Theory. As the authorship rights weren't acquired by the Belarus-based TV people properly, the show was considered a plagiarism. The whole deal wasn't brought to court, however, and the production was stopped after making of 4 episodes.

The main characters were named Leonard and Sheldon to commemorate a great actor and producer Sheldon Leonard who is responsible for making dozens of well-known films and TV projects.

Howard wears a belt, on which, in various episodes, one can spot logos of different superheroes from movies, TV shows, and comic books.
