Unfortunately Season 2 of The Big Bang Theory is not available online in the United States. Warner Bros., the company who produce & distribute the show, have decided not to put further episodes of The Big Bang Theory online because they want to protect future syndication deals. You can still get Season 1 of The Big Bang Theory on Amazon Unbox.
Fans in the United Kingdom can see episodes of The Big Bang Theory on 4oD, and can purchase episodes through Tesco Digital and iTunes.
