Big changes are going to happen in the upcoming episodes of The Big Bang Theory Season 9.

The show has been doing well since it first premiered on September 24, 2007 on CBS. Based on the friendship and developing relationships between 5 characters, the Big Bang Theory was created by Chuck Lorre and Bill Prady.

It has now grown to include more characters, the most popular at the moment being Amy and Sheldon. The show has been nominated for several awards and Jim Parsons, who plays Sheldon Cooper, has won two Emmy’s and a Golden Globe for best actor.

The show mainly revolves around Sheldon Cooper and Leonard Hofstadter, two room-mates and their friends and love interests. Leonard is married to another popular character of the show, Penny, who lives next door.

In the final episode of Season 8, Amy breaks up with Sheldon just as he was going to propose to her. Season 9 began with the couple broken-up, but the chemistry between them still remained. In episode 8 of Season 9, Amy went out on a date only to realize that her date was more in love with Sheldon than her.
