The Big Bang Theory All TV Seasons

: The Big Bang Theory, Season 117 Sep 200717 Episodes
Meet two brainiacs with a lot to learn. Leonard and Sheldon can tell their quarks from their quantum physics, but have no clue how women add up. Leave it to their pretty new neighbor, just off a messy breakup, to teach them a thing or two in The Big Bang Theory.

: The Big Bang Theory, Season 522 Sep 201124 Episodes
Leonard and Sheldon are brilliant physicists – wizards in the laboratory, but socially inept outside of it. Enter beautiful, free-spirited neighbor, Penny, who aims to teach them a thing or two about life. While Leonard spends his days looking for love, Sheldon is quite content video-chatting with platonic partner and neurobiologist Amy Farrah Fowler (Mayim Bialik), or playing Star Trek three-sided chess with their ever-expanding universe of friends, including fellow scientists Raj Koothrappali and Howard Wolowitz, and Howard’s new fiancée, the adorable micro-biologist/waitress, Bernadette (Melissa Rauch). Emmy®-nominated for Outstanding Comedy Series as well as Outstanding Lead Actor in a Comedy Series for both Jim Parsons and Johnny Galecki, this award-winning comedy is nothing short of genius!

: The Big Bang Theory, Season 627 Sep 201226 Episodes
The CalTech geniuses of The Big Bang Theory return for season six after being thrown for a bell curve in the phenomenally funny fifth season of the hit show. In “TV’s top-rated comedy” (New York Post), Leonard has to “debug” his relationship with Penny once more after accidentally proposing to her in the heat of the moment, while Sheldon, Howard, and Raj continue to discover the feminine mystique is something that cannot be easily graphed or calculated. With even greater personal contact with his not girlfriend but “friend-who-happens-to-be-a-girl” Amy Farrah Fowler, Sheldon might have to make even more begrudging amendments to his “Relationship Agreement” while Raj continues to look for a girl as nice as Siri, and Howard gets ready for splashdown in both his NASA space travels and wedding to the spirited Bernadette.

: The Big Bang Theory, Season 220 Sep 200823 Episodes
Leonard and Sheldon are brilliant physicists, the kind of 'beautiful minds' that understand how the universe works. But none of that genius helps them interact with people, especially women. All this begins to change when a free-spirited beauty named Penny moves in next door. Sheldon, Leonard's roommate, is quite content spending his nights playing Klingon Boggle with their socially dysfunctional friends, fellow Caltech scientists Wolowitz, Koothrappali and Winkle. However, Leonard sees in Penny a whole new universe of possibilities ... including love.

: The Big Bang Theory, Season 726 Sep 201333 Episodes
Doctors Leonard Hofstadter & Sheldon Cooper (Johnny Galecki & Jim Parsons) are brilliant physicists – masterminds of their CalTech laboratories, but socially challenged in the non-theoretical real world. Enter beautiful, street-smart neighbor, the actress/waitress Penny (Kaley Cuoco), who aims to teach them a thing or two about life. Despite their on-again, off-again relationship in the past, Leonard believes he’s found true love with Penny. Even Sheldon has grown comfortable with a female companion, entering into a signed “Relationship Agreement” with neurobiologist Amy Farrah Fowler (Mayim Bialik). In their free time, Leonard and Sheldon continue to enjoy weekly trips to the comic book store and fantasy role-playing games with their ever-expanding universe of friends, including fellow scientists Rajesh Koothrappali (Kunal Nayyar), Howard Wolowitz (Simon Helberg), and Howard’s microbiologist wife, Bernadette (Melissa Rauch).

: The Big Bang Theory, Season 321 Sep 200923 Episodes
The physics of funny is back for year three! At work, CalTech doctors Sheldon Cooper and Leonard Hofstadter and their uber-geek pals Howard Wolowitz and Rajesh Koothrapali rule over the rules of the cosmos. At home, however, on the mean streets of Pasadena – whether it’s dating or day-to-day survival – the real world conquers them. And with one of the universe’s greatest mysteries living next door – an attractive neighbor named Penny – they’ve got their work cut out from them. Emmy® nominee Jim Parsons stars alongside Johnny Galecki, Kaley Cuoco and more in the third laugh-filled season from creator/producers Chuck Lorre (Two and a Half Men) and Bill Prady (Dharma & Greg) that proves the hypothesis that comedy is both an art and a science!

: The Big Bang Theory, Season 423 Sep 201024 Episodes
Worlds collided last season, when a love affair with Penny (Kaley Cuoco) opened a big, wide, wonderful world of romance for Leonard (Johnny Galecki). Sheldon (Jim Parsons), of course, likes the world just the way it is, thank you. And now, that Leonard and Penny have broken up again, all three can test all the variables of being neighbors once more. The result makes for a zany comic triangle with brainy, clueless Sheldon and practical, grounded Penny hilariously vying for the role of hypotenuse to level-headed Leonard. Add to this combustible chemistry, the terminally under-spoken Raj, the over-spoken Howard and guest stars like Apple’s Steve Wozniak and more and you’ve got all the fun of a series that only gets better. Entertainment Weekly raves that the show “has transformed from a cute comedy about eggheads and their hottie neighbor into an addictive ensemble piece that could be this decade’s answer to Friends.”

Prepare to enter phase nine of television’s perpetual laughter experiment as THE BIG BANG THEORY successfully fuses the elements of science and sitcom. Our two genius roommates – Leonard and Sheldon ¬– and their friends are back once again (smarter, but no wiser). Last season, Sheldon went soul-searching (on a train, of course) and was prepared to make some substantial revisions on his Relationship Agreement with Amy, when everything changed. Leonard, meanwhile, was off to Vegas with Penny to finally tie the knot in the season finale. Howard finds himself alone with Bernadette after the sudden passing of his mother; while Raj is not only talking to women – he’s getting exclusive with Emily (Laura Spencer). Together, they will all learn that life is far more complicated outside of the lab as love and friendship never produce predictable results!

The universe of Drs. Leonard Hofstadter and Sheldon Cooper is endlessly complicated and hilarious as The Big Bang Theory enters the tenth dimension! Last season, Leonard and Penny went from next-door neighbors to next-door newlyweds with a nuptial excursion to Vegas. This season, they find themselves in a repeating paradigm as they re-create their wedding – this time with family including Penny’s mother (Katey Sagal) and brother (Jack McBrayer) and Leonard’s parents (Christine Baranski & Judd Hirsch). Meanwhile, the Relationship Agreement between Sheldon and Amy added an entirely new subsection with their annual coitus clause. Also, gravitating in their universe, Howard and Bernadette prepare for the arrival of a little Wolowitz, while Raj finds himself juggling not one, but two girlfriends. Prepare to test a new hypothesis of inspired comedy that’s nothing short of genius in Season Ten!
