Johnny Galecki and Sara Gilbert both selected the episode "The Hamburger Postulate" as a Primetime Emmy Award submission for Outstanding Lead Actor in a Comedy Series and Outstanding Guest Actress in a Comedy Series, respectively, at the 60th Primetime Emmy Awards, but both ended up not receiving a nomination. Jim Parsons selected the episode "The Pancake Batter Anomaly" as a Primetime Emmy Award submission for Outstanding Lead Actor in a Comedy Series at the 60th Primetime Emmy Awards, but ended up not receiving a nomination.
The lives of physicists Dr. Leonard Hofstadter and Dr. Sheldon Cooper are shaken up when an attractive young aspiring actress from Omaha, Nebraska named Penny moves into the apartment across the hall from theirs. Leonard begins to become hopelessly enamored of Penny, while she feels only platonic affection for him; as a result, she finds herself putting up with his closest and ever-present friends: his roommate, Sheldon, who appears borderline obsessive-compulsive; engineering whiz Howard Wolowitz, a desperately sex-crazed mama's boy who thinks that his 1960s-style clothing and hairstyle give him an air of cool hipness; and Dr. Rajesh "Raj" Koothrappali, who will not speak to her as he is too shy to talk to women (a case of selective mutism), unless intoxicated in which case he becomes a smooth talking yet highly overly aggressive womanizing flirt.
During Season One, Sheldon loses his job for insulting his new boss, finds his ego bruised by a child prodigy, becomes unable to bear being part of a lie that Leonard has told, and is always attacking the world with a relentless need to assert his supremacy. Rajesh first learns that he can talk to women, but only when he is drunk, and Penny and Leonard finally go out in the season finale. It is so far the only season not to feature John Ross Bowie as the recurring character Barry Kripke and Kevin Sussman as Stuart Bloom.
The program's initial pilot, developed for the 2006/07 television season, was substantially different from its current form. Only Johnny Galecki and Jim Parsons were in the cast, and their across-the-hall neighbor Katie was envisioned as "a street-hardened, tough-as-nails woman with a vulnerable interior". Katie was played by actress Amanda Walsh. They also had a female friend called Gilda (played by Iris Bahr). The program's original theme music was also different, using Thomas Dolby's hit "She Blinded Me with Science". The program was not picked up, but the creators were given an opportunity to revise it, bringing in the remaining leading cast and retooling the show to its current format. The original unaired pilot has never been released on any official format, but copies of it are on the internet with various collectors.
The second pilot of The Big Bang Theory was directed by James Burrows, who did not continue with the show. This reworked pilot led to a 13-episode order by CBS on May 14, 2007. Prior to its airing on CBS, the pilot episode was distributed on iTunes free of charge. The show premiered September 24, 2007, and was picked up for a full 22-episode season on October 19, 2007.
Production on the show was halted on November 6, 2007, due to the 2007–2008 Writers Guild of America strike, only to be replaced by a short-lived sitcom, Welcome to the Captain on February 4, 2008, but returning on March 17, 2008, in an earlier time slot with nine new episodes.

|After an unsuccessful visit to the high-IQ sperm bank, Dr. Leonard Hofstadter and Dr. Sheldon Cooper return home to find aspiring actress Penny is their new neighbor across the hall from their apartment.

Leonard invites Penny to his and Sheldon's apartment for Indian food, where she asks to use their shower since hers is broken. While wrapped in a towel, she gets to meet their visiting friends Howard Wolowitz, a wannabe ladies' man who tries to hit on her, and Rajesh Koothrappali, who is unable to speak to her as he suffers from selective mutism in the presence of women. Leonard is so infatuated with Penny that, after helping her use their shower, he agrees to retrieve her TV from her ex-boyfriend Kurt. However, Kurt's physical superiority overwhelms Leonard's and Sheldon's combined IQ of 360, and they return without pants or TV. Penny, feeling bad, offers to take the guys out to dinner, initiating a friendship with them.|

When Sheldon and Leonard drop off a box of flat pack furniture that came for Penny, Sheldon is deeply disturbed at how messy and disorganized her apartment is. Later that night, while Penny sleeps, the obsessive-compulsive Sheldon, unable to sleep, sneaks into her apartment to organize and clean it. Leonard finds out and reluctantly helps him. The next morning, Penny is furious to discover they had been in her apartment. Sheldon tries to apologize to Penny but fails by remarking that Leonard is a "gentle and thorough lover". Later, Penny encounters Raj in the hallway. Though he cannot talk to Penny, she calms down whilst telling him about the issue, reasoning the guys were just trying to help her, and hugs Raj. Then Leonard apologizes, prompting Penny to forgive and hug him.

When he sees Penny kissing a man in front of her apartment door, Leonard is devastated that she has "rejected" him. The guys persuade him to date someone at work, so he approaches fellow scientist Leslie Winkle. In an experiment to strip the usual dating procedure to its essentials, she suggests fast forwarding to a kiss. She finds their kiss good but unexciting, so she turns him down. As Leonard becomes more depressed, thinking of buying a cat (hypoallergenic in view of Sheldon's asthma - though in later episodes Leonard is the one with asthma), Sheldon points out Leonard was not actually rejected by Penny as he never asked her out, so Leonard asks her out to dinner. As she misinterprets this as an invitation to hang out with all the guys, he devises reasons for their absence from the date. Penny says the man Leonard saw was not her boyfriend: casual weekend sex helps her get over relationships. Leonard, excited, regains his confidence, but he accidentally hurts himself and Penny has to take him home. In the end, Leonard does not find the courage to reveal his true feelings to Penny, though she suspected what he was up to.

At the university Sheldon is fired from his job as a physicist after insulting his new boss Dr. Eric Gablehauser. Sheldon's change of circumstance triggers a downward spiral of depression in which he fails to improve scrambled eggs, develops luminous fish for nightlights, and weaves on a hand loom. Worried, Leonard calls Sheldon's mother, Mary Cooper. When she visits, the men realize she is the complete opposite of their expectations: she is sweet, down-to-earth, a devout Christian, and a loving and caring mother. Mary finally forces Sheldon to apologize, who is given his job back after she flirts with Dr. Gablehauser.

The guys, eating at the Cheesecake Factory where Penny works, are approached by Leslie Winkle. She wants Leonard to play cello in her string quartet as the other players are uncomfortable near the current cellist who was possibly irradiated at work. After the quartet practise in Leonard and Sheldon's apartment, Leslie seduces Leonard for the night, making Sheldon so uneasy that he repeatedly asks Penny's advice. Penny later congratulates Leonard, who tries to figure out what she meant. Leonard decides to pursue a real relationship with Leslie rather than an imaginary one with Penny, but at her lab, Leslie makes it clear she is not interested in a relationship: she just needed him for a one-night stand to satisfy her sex drive - which is now satisfied until New Year. Leonard later tells Penny, who reassures him and walks away smiling.

Penny invites the guys to her Halloween party. They at first decline as they do not dance, but accept when costumes are mentioned. At the party they have problems socializing: Sheldon is unable to explain his Doppler effect costume since none of Penny's friends are physicists or smart enough to understand it; Raj (dressed as Thor) cannot speak to women; Howard as Robin Hood is mistaken for Peter Pan; and Leonard (dressed as Frodo Baggins from The Lord of the Rings) is insecure. Penny's ex-boyfriend Kurt (underdressed as a very tall, muscular caveman) later shows up and aggressively confronts Leonard, causing him (and later Penny) to leave. Penny goes to check on Leonard and apologizes for Kurt's behavior. She is very upset, but Leonard tells her she is perfect, and they kiss, though Penny confesses she is drunk. They kiss again, in sight of Kurt, Leonard saying "That's how we roll at the Shire!" before locking his apartment door in panic. Meanwhile, Howard cannot find Raj, who is at home sleeping with a girl who finds him to be a "very good listener".

Next day, Howard invites Christy to move in with him (and his mother), taking up all his time. Distraught at the odd number in the group, Sheldon invites Penny to play Halo again, but she prefers to go dancing. The guys believe their group is falling apart and go to speak to Howard.

She practices mixing drinks with the guys, and they discover Raj is able to speak to women after drinking alcohol. They decide his date should be at Penny's restaurant so she and the guys can keep an eye on Raj's behavior when drinking. On his date, Raj becomes an obnoxious drunk.

Sheldon appears at the conference and tries to discredit Leonard's presentation by attempting to "blow up" Leonard's head with his mind à la the movie Scanners, starting a physical altercation between the two. Howard films the fight on his cellphone and puts it on YouTube, but angers Penny by also posting a photo on Facebook of her sleeping on his shoulder during the presentation, entitled "Me and my girlfriend".

Sheldon loses faith in his own research and annoys his friends by criticizing their work more than ever and forcing his own contributions on them. Finding his physics work useless, he aims for the Nobel Peace Prize by attempting to solve all Middle East conflicts, but he annoys everyone, including a Jewish professor, with his proposal that an exact duplicate of Jerusalem be built in the Mexican desert. The others, tired of Sheldon's behavior, decide to distract Kim with girls of the same age. Their plan unexpectedly works at Kim's welcome party, and Kim leaves with a blonde 15-year-old.

This upsets Leonard, who decides to sell all his collectibles. His friends try to dissuade him, but they also want his collectibles and argue over who should get what. Sheldon later accuses Penny of hypocrisy, pointing out her own love of such things as Hello Kitty or Care Bears.

Penny learns that Leonard has never had a birthday party, as his parents did not believe in celebrating anything other than achievements. She decides to throw him a surprise party, and blackmails Sheldon to join in by threatening to draw a smiley face on each of his mint condition comic books. However, on the day of the party, Penny discovers Sheldon has not yet bought a present, so she has to drive him to a computer store to buy one. Meanwhile, Howard has the task of keeping Leonard out of his apartment before the party. Howard pretends to eat a peanut bar, to which he is allergic, so that Leonard will drive him to the emergency room. However, Sheldon's lack of focus at the computer store means Howard has to distract Leonard even longer, and he eventually actually eats the peanut bar, swelling up in a severe allergic reaction. After several hours at the hospital, Howard and Leonard arrive back at the apartment to find the party has ended, though Penny does kiss Leonard.

Penny furiously breaks up with Mike after he posts details of their sex life on his blog, while Sheldon, determined to prove that the Chinese restaurant uses oranges instead of tangerines in their "Tangerine chicken", asks Howard to teach him Mandarin. When Penny laments her choice of men, Leonard awkwardly asks her out. After a few days, both worry that this relationship could ruin their friendship, and each seeks Sheldon's advice. Sheldon uses the "Schrödinger's cat" thought experiment to explain that the date has both "good" and "bad" possible outcomes, and the only way to determine which outcome is to go on the date. When Leonard arrives to pick up Penny, he mentions the thought experiment and kisses her passionately. She concludes that "the cat is alive" and they leave for dinner. Leonard and Penny go to the Chinese restaurant, but they leave before entering on seeing Sheldon arguing with the owner in Mandarin, and doing it very badly, disturbing the patrons.
Title reference: The Chinese Tangerine chicken which Sheldon believed was actually prepared with oranges.
The Big Bang Theory initially received mixed reviews, receiving 52% "rotten" score on review aggregator Rotten Tomatoes, based on 23 reviews, with the critics consensus reading "The Big Bang Theory brings a new class of character to mainstream television, but much of the comedy feels formulaic and stiff." It also received a 57-point score on review aggregator Metacritic, indicating "mixed or average reviews", based on 23 reviews.
Tom Shales of The Washington Post gave the show a positive review, saying "Big Bang is the funniest new sitcom of the season". Robert Bianco of USA Today also gave the show a positive review, saying "This may not be the sitcom breakthrough for which we've all been hoping, but Lorre has produced a first episode that leaves you eager to try the second".
David Bianculli of New York Daily News criticized the dialogue, particularly when the male characters explain jokes, writing that "People tuning in to Big Bang may not all be Mensa members, but they won't all be idiots, either", Henry Goldblatt of Entertainment Weekly criticized the premise and plot of early episodes, writing that "To call this a one-joke sitcom would be a stretch", and Tim Goodman of San Francisco Chronicle criticized the stereotypes presented in the characters, and wrote that "the writing here is so moronic and the situations so forced and mundane".
