The Big Bang Theory is an American sitcom created by Chuck Lorre and Bill Prady, both of whom serve as executive producers on the show, along with Steven Molaro. All three also serve as head writers. It premiered on CBS on September 24, 2007.[3]

The show is centered on five characters: roommates Leonard Hofstadter and Sheldon Cooper, two physicists who work at the California Institute of Technology (Caltech); Penny, a blonde waitress and aspiring actress who lives across the hall; and Leonard and Sheldon's equally geeky and socially awkward friends and co-workers aerospace engineer Howard Wolowitz and astrophysicist Rajesh Koothrappali. The geekiness and intellect of the four guys is contrasted for comic effect with Penny's social skills and common sense.[4][5] Three other supporting characters have also been promoted to starring roles: Leslie Winkle, a physicist colleague at Caltech and, at different times, a lover of both Leonard and Howard; Bernadette Rostenkowski, Howard's fiancée, who is a microbiologist and part-time waitress alongside Penny; and Amy Farrah Fowler, a neurobiologist who joins the group after being matched to Sheldon on a dating website.

The show is produced by Warner Bros. Television and Chuck Lorre Productions.[6] In August 2009, the sitcom won the best comedy series TCA award and Jim Parsons (Sheldon) won the award for individual achievement in comedy.[7] In 2010, the show won the People's Choice Award for Favorite Comedy, while Parsons won a Primetime Emmy Award for Outstanding Lead Actor in a Comedy Series.[8] On January 16, 2011, Parsons was awarded a Golden Globe for Best Performance by an Actor in a Television Series – Comedy or Musical, an award that was presented by co-star Kaley Cuoco (Penny). On September 18, 2011, Parsons was again awarded an Emmy for Best Actor in a Comedy Series.

When the third season premiered on September 21, 2009, Big Bang Theory ranked as CBS's highest-rated show of that evening in the adults 18–49 demographic (4.6/10), along with a then-series-high 12.83 million viewers.[9] On May 19, 2010, it was announced that CBS would be moving the show to Thursdays at 8:00 ET for the 2010–2011 schedule. On January 12, 2011, CBS announced that the show had been renewed for an additional three years, extending it through the 2013–2014 season.[10] The fifth season premiered on September 22, 2011, in its usual time slot with two back-to-back episodes.[11][12]

Production

The show's initial pilot, developed for the 2006–07 television season, was substantially different from its current form. The only characters from the initial pilot that were kept for the reshot pilot for the series were Leonard and Sheldon (portrayed by Johnny Galecki and Jim Parsons respectively). The cast was rounded off by two female leads: Canadian actress Amanda Walsh as Katie, "a street-hardened, tough-as-nails, woman with a vulnerable interior" who the boys meet after she breaks up with her boyfriend and invite to live in their apartment (Katie was effectively replaced by Penny in the second pilot);[13][14] and Iris Bahr as Gilda, a scientist colleague and friend of the boys who was threatened by Katie's presence. The initial pilot used Thomas Dolby's hit "She Blinded Me With Science" as theme music.

The series was not picked up, but the creators were given an opportunity to retool the show and produce a second pilot. They brought in the remaining cast and retooled the show to its final format. The original unaired pilot has never been officially released, but it has circulated on the Internet. On the evolution of the show, Lorre said "We did the 'Big Bang Pilot' about two and a half years ago, and it sucked... but there were two remarkable things that worked perfectly, and that was Johnny and Jim. We rewrote the thing entirely, and then we were blessed with Kaley and Simon and Kunal." As to whether the world will ever see that original pilot, maybe on a DVD, Lorre said "Wow that would be something, we will see. Show your failures..."[15]

The first and second pilots of The Big Bang Theory were directed by James Burrows, who did not continue with the show. The reworked second pilot led to a 13-episode order by CBS on May 14, 2007.[16] 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.[17] However, production was halted on November 6, 2007 due to the Writers Guild of America strike. The series returned on March 17, 2008 in an earlier time slot[18] and ultimately only 17 episodes were produced.[19][20] After the strike ended, the show was picked up for a second season airing in the 2008–2009 season, premiering in the same time slot on September 22, 2008.[21] With increasing ratings, the show received a two-year renewal through the 2010–11 season.[22][23] Since then, the show has been picked up for three more seasons.[24]

David Saltzberg, a professor of physics and astronomy at the University of California, Los Angeles, checks scripts and provides dialogue, mathematics equations, and diagrams used as props.[4] According to executive producer/co-creator Bill Prady, "We're working on giving Sheldon an actual problem that he's going to be working on throughout the [first] season so there's actual progress to the boards ... We worked hard to get all the science right."[5]

Several of the actors in The Big Bang Theory worked together previously on Roseanne including Johnny Galecki, Sara Gilbert, and Laurie Metcalf (who plays Sheldon's mother, Mary Cooper). Additionally, Lorre was a writer on the series for several seasons.

Theme song

File:BNL BigBang.jpg
Single cover for "Big Bang Theory Theme" by Barenaked Ladies (2007)

The Canadian alternative rock band Barenaked Ladies wrote and recorded the show's theme song, which describes the history and formation of the universe and the Earth. Ed Robertson, lead singer and guitarist in the band, was asked by Lorre and Prady to write a theme song for the show. Having been asked to write songs for other films and shows only to have them rejected in favor of another artist's, Robertson agreed to write a theme only after learning that he was the sole writer that Lorre and Prady had asked. He drew inspiration from Simon Singh's book, Big Bang, which he had coincidentally just finished reading.[25][26]

On October 9, 2007, a full-length (1 minute and 45 seconds) version of the song was released commercially.[27] In a 2010 issue of TV Guide, the show’s opening title sequence ranked No.6 on a list of television's top 10 credits sequences, as selected by readers.[28]

Production costs

For the first three seasons, Johnny Galecki, Kaley Cuoco and Jim Parsons, the three main stars of the show, received at most $60,000 per episode. The salary for the three went up to $200,000 per episode for the fourth season. According to their contracts, their pay will go up an additional $50,000 per episode in each of the following three seasons, culminating in $350,000 per episode in the seventh season.[29][30]

Main cast

Cast of characters in The Big Bang Theory. From left: Howard Wolowitz, Leonard Hofstadter, Penny, Sheldon Cooper and Rajesh Koothrappali.

These actors have been credited in all episodes of the series:

  • Johnny Galecki[31] as Leonard Hofstadter, Ph.D. – An experimental physicist with an IQ of 173, he received his Ph.D. when he was 24 years old. The straight man of the series, he shares an apartment with colleague and friend Sheldon Cooper. The writers immediately implied potential romance between him and neighbor Penny, and their sexual tension is frequently explored.
  • Jim Parsons[32] as Sheldon Cooper, Ph.D., Sc.D. – Originally from East Texas, he was a child prodigy with an eidetic memory who began college at the age of 11 (after completing the fifth grade), started graduate studies at 14, and earned a Ph.D. at 16. A theoretical physicist focusing on quantum mechanics and string theory, he has a master's degree, a Ph.D. an Sc.D., and an IQ of 187. He exhibits a strict adherence to routine; a lack of understanding of irony and sarcasm; he is also uninterested in many of the romantic hijinks of his friends. Sheldon shares an apartment with Leonard Hofstadter, across the hall from Penny, and relies on both for advice in social situations. In the fourth season, he begins a relationship with Amy Farrah Fowler, who becomes his first girlfriend.
  • Kaley Cuoco[33] as Penny – The "born and raised in Omaha, Nebraska" blonde who lives across the hall from Sheldon and Leonard. She is pursuing a career in acting, and has been on casting calls and auditions but has not been very successful thus far. To pay the bills, she is a waitress and occasional bartender at The Cheesecake Factory. To date, her last name has not been revealed. She dated Leonard at the end of the first season, and throughout the third and fifth seasons.[34]
  • Simon Helberg[35] as Howard Wolowitz, M.Eng.[36] – He works as an aerospace engineer. He is Jewish, and lives with his mother. Unlike Sheldon, Leonard, and Raj, Howard lacks a Ph.D. He defends this by pointing out that he has a master's degree in Engineering from MIT and that the apparatus he designs are launched into space, unlike the purely abstract work of his friends. He provides outrageous pick-up lines and fancies himself a ladies' man with suitably unimpressed reactions from Penny; however, he has shown limited success with other women. He claims to be a polyglot. He dates and later becomes engaged to Bernadette Rostenkowski. In the 5th season, he is training as an astronaut.
  • Kunal Nayyar[37] as Rajesh Koothrappali, Ph.D. – Originally from New Delhi, India, and works as a particle astrophysicist at Caltech.[38] His family is very well off. He communicates with his parents, Dr. and Mrs. V.M. Koothrappali, via webcam. He is very shy around women and is physically unable to talk to them unless he drinks alcohol (or thinks he has been drinking alcohol). However, he has often had better luck with women than his overly-confident best friend Howard. During the fourth season, his sister Priya (Aarti Mann) stays with him and became Leonard's girlfriend.

These actors were first credited as guest stars and later promoted to main cast. However, even after promotion, they are only credited in episodes in which they appear:

  • Sara Gilbert as Leslie Winkle, Ph.D. (recurring seasons 1–3, starring part of season 2)[39][40] – a physicist who works in the same lab as Leonard. In appearance she is essentially Leonard's female counterpart, equipped with the black framed glasses and sweat jackets. She is an enemy of Sheldon's, due to their conflicting scientific theories. Though they both consider each other to be intellectually inferior, Leslie is much wittier than Sheldon, regularly calling him "dumbass", and usually bests him in their repartee. Leslie has had casual sex with Leonard and later Howard; in the case of the former, it reunites Gilbert and Galecki together on-screen after the two played the on-screen couple of Darlene Connor and David Healy respectively during the run of Roseanne. Gilbert was promoted to a main cast member during the second season, but was demoted again because producers could not generate enough content for the character.[39] Gilbert left the series after season 3 concluded to focus her efforts on The Talk, on which she serves as executive producer for CBS.
  • Melissa Rauch as Bernadette Rostenkowski, Ph.D. (recurring season 3 5–14, starring since season 4 episode 4)[41] – a young woman who is initially a waitress and co-worker of Penny paying her way through graduate school microbiology studies, she defends her doctoral thesis and lands a high-paying science position at the end of season 4. Bernadette is introduced to Howard by Penny. At first she and Howard do not get along, as they appear to have nothing in common. When they find out that they both have overbearing mothers, they feel a connection. They became engaged near the end of season 4.
  • Mayim Bialik as Amy Farrah Fowler, Ph.D. (guest episode 23 season 3 until season 4 episode 5, starring since season 4 episode 8)[42] – a woman Raj and Howard met on an online dating site after secretly setting up an account using Sheldon's name and information. The site matches her to Sheldon, and the two share many similar traits. Once she and Sheldon meet, she becomes, as Sheldon puts it, a girl who is his friend, but not his "girlfriend". In Season Five, Amy made Sheldon jealous by going on a date with comic book store owner, Stuart, causing Sheldon to solidify their relationship as boyfriend/girlfriend. Sheldon then insisted that Amy sign a 31-page "Relationship Agreement." She also believes she and Penny are best friends, a sentiment Penny doesn't seem to share but respectfully indulges. Her admiration for Penny has at times bordered on attraction. Amy Fowler has a Ph.D. in neurobiology, while Bialik herself has a doctorate in neuroscience; in the season 1 episode "The Bat Jar Conjecture", Raj suggests recruiting the real-life Bialik to their Physics Bowl team.

Elements of the show

Science

Much of the show focuses on science, particularly physics. The four main male characters are employed at Caltech and have science-related occupations. The characters frequently banter about scientific theories or news (notably around the start of the show), and make science-related jokes.

Science has also interfered with the characters’ romantic lives. Leslie broke up with Leonard when he sided with Sheldon in his support for string theory rather than her support for loop quantum gravity. When Leonard joined Sheldon, Raj and Howard on a three-month Arctic research trip, it separated Leonard and Penny at a time their relationship was budding. When Bernadette took an interest in Leonard's work, it made both Penny and Howard jealous and resulted in Howard confronting Leonard, and Penny asking Sheldon to teach her physics. Sheldon and Amy also briefly ended their relationship after an argument over which of their fields was superior to the other's.

Sci-fi, fantasy and comic book fandom

The four main male characters are all avid sci-fi, fantasy, and comic book fans and memorabilia collectors.

Star Trek in particular is frequently referenced and Sheldon identifies strongly with the character of Spock; when he is given a used napkin signed by Leonard Nimoy as a Christmas gift from Penny he is almost overwhelmed with excitement and gratitude ("I possess the DNA of Leonard Nimoy?!"). All four male characters can speak Klingon to varying degrees—the opening of the episode "The Panty Piñata Polarization" shows them playing "Klingon Boggle". (Star Trek: The Original Series cast member George Takei has made a cameo. Star Trek: The Next Generation cast members Wil Wheaton, Brent Spiner, and LeVar Burton have all had cameos as themselves.) In one episode, Sheldon also admits that despite considering Star Trek V: The Final Frontier basic dumb sequel bad, he personally found The Motion Picture even more boring.

Wednesday night is the group's designated "comic book store night", the store in question being run by fellow geek and recurring character Stuart. On a number of occasions, the group members have dressed up as pop culture characters, including The Flash, Aquaman, Frodo Baggins, Superman, Batman, Spock, the Doctor, Green Lantern, and Thor (albeit as the original Norse god and not the Marvel Comics character). As a consequence of losing a bet to Stuart in the episode "The Wheaton Recurrence", the group members are forced to visit the comic book store dressed as Catwoman, Wonder Woman, Batgirl, and Supergirl. Sheldon often wears t-shirts depicting the Batman, Superman, Flash, Greatest American Hero, or Green Lantern logos.

The group are also fans of the Indiana Jones series, even willing to spend several hours outside of a theater to watch the film with 21 seconds of new footage.

Leonard and Penny's relationship

One of the recurring themes is the relationship between Leonard and Penny. Leonard becomes attracted to Penny within seconds of seeing her in the pilot episode. The season frequently featured Leonard's attraction to Penny as a basis for humor. Leonard and Penny briefly date at the start of the second season; however, Penny quickly breaks up with Leonard because she is afraid that her educational attainments aren't good enough for Leonard and that he may become bored.

The two date other people throughout the second season, but clearly still have feelings for each other. When Leonard returns from a 3-month expedition to the North Pole in the season 3 premiere, they commence a relationship which lasts for most of the season until Leonard tells Penny that he loves her and she realizes she cannot say it back, and she reluctantly breaks up with him.

Again, both Leonard and Penny go on to date other people; most notably with Leonard dating Raj's sister Priya for much of season 4. Penny has shown regret towards her decision to break up with Leonard by admitting to her girlfriends that she misses Leonard. She also exhibits jealousy towards Priya, especially after Priya demanded Leonard stay away from her. After dating Leonard, Penny also has negative reactions to her male dates who are not very intelligent.

Eventually, as the episodes roll on, Leonard became more and more interested in Priya. However she seemed to become less and less interested in Leonard as they went on dating. Later in the season, Leonard is over at Raj's apartment with Priya, making out with her, when Priya's parents call from India. Leonard is told to leave the room as Priya answers the call. Unknowing of Leonard's presence or his secret relationship with Priya, her parents state that they will be so happy when Priya moves back to India. Leonard comes in, shouting out that he is shocked she is moving back to India, and assumes it means he and Priya are breaking up.

Leonard goes home to his apartment, where Raj has been sleeping because of Leonard staying at Raj's apartment. Penny and Raj, while enjoying a friendly evening, got drunk and ended up in bed together; however, nothing happened physically between them. Leonard finds out when they emerge and assumes the worst; it is only later he learns the truth - nothing happened.

In season five, Leonard resumes his relationship with Priya online. It seems to work for Leonard, but he is conflicted when he meets Alice, a girl who is really into him, at the comic book store. Leonard decides he must be faithful to Priya, ending things with Alice. Leonard confesses to Priya about going out with Alice, only to discover that Priya has slept with an ex-boyfriend, and they break up.

Penny is still single and dating, though when drunk has confessed that she regrets breaking up with Leonard. In "The Ornithophobia Diffusion" Leonard and Penny go to the movies as friends. Leonard decides that since they are no longer dating he can be honest and does not have to pay for everything or do whatever Penny wants to make Penny like him and have sex with him. The two bicker all evening and sabotage each other's attempts to chat up people in the bar. Penny decides that she likes the new more assertive Leonard. Leonard sees this as another opportunity to grovel and try to get Penny to sleep with him, so she leaves.

On the spur of the moment in "The Recombination Hypothesis", Leonard asks Penny out on a date after he imagined what getting back with her might be like. Their real date ends successfully, and they agree to try to renew their relationship slowly in "The Beta Test Initiation".

Sheldon and Amy's relationship

A new recurring theme is the status of Sheldon and Amy Farrah Fowler, Ph.D., a neurobiologist whom Raj and Howard found as a possible match for Sheldon through an internet dating service (without Sheldon's knowledge). By Sheldon's own admission, she is most like him by any standard. Like him, she has previously avoided relationships (whether romantic or otherwise is unclear), and only participated in the online dating herself to fulfill an agreement with her mother that she date at least once a year (in exchange her mother does not discuss her lack of a dating life, plus she gains use of her mother's George Foreman Grill).

During the four months of their relationship (taking place off-screen between seasons 3 and 4), they communicated on a daily basis via text messages, email and Twitter, but never saw each other in person. Sheldon, however, did not consider Amy his girlfriend. Penny later suggests that they should go on a date and ends up driving them, having dinner with them in "The Robotic Manipulation." Penny occasionally refers to Sheldon and Amy collectively as "Shamy."

In the episode "The Agreement Dissection", Amy, Penny, and Bernadette decide to take Sheldon dancing. Sheldon dances only with Amy, which he does not mind. He later follows Amy back to her apartment. They talk for a few minutes before she kisses him on the lips. Instead of getting annoyed, Sheldon just says "Fascinating."

In "The Flaming Spittoon Acquisition", after Amy agrees to go on a date with Stuart the comic book store owner, Sheldon asks Amy to be his girlfriend with no other change to their current relationship. Soon after, he draws up "The Relationship Agreement" to verify the ground rules of him as her boyfriend and her as his girlfriend (similar to his "Roommate Agreement" with Leonard). Amy agrees but later regrets not having a lawyer read through it.

After Penny and Bernandette go wedding shopping without Amy in "The Isolation Permutation", Sheldon comforts a depressed Amy by cuddling with her on her couch; however, Amy first suggests that they have sex.

Religion

Religion plays a minor role in the series. Sheldon was raised in a fundamentalist Christian household. He refers to his childhood as "hell", and a recurrent theme is his conflict with his devout mother, Mary, whose creationist beliefs often clash with Sheldon's understanding of evolution. In "The Lunar Excitation", Sheldon mentions his promise to Mary to attend church once a year. In "The Wheaton Recurrence", after scoring a spare in bowling, Sheldon happily exclaims "Thank you, Jesus! ...as my mother would say." In the episode "The Zarnecki Incursion", Sheldon can be heard exclaiming "Why hast thou forsaken me, o deity whose existence I doubt?"

Howard and Raj are Jewish and Hindu, respectively, and semi-observant, apparently defying many religious customs without worry. They frequently flout dietary prohibitions and tend to give each other grief about them--Raj quotes from the Talmud after Howard eats pork, and Howard sharply says he holds his tongue when Raj eats a Big Mac. Still, Raj mentions reincarnation and karma, and Howard celebrates at least some Jewish holidays and refuses to get tattoos so he "can be buried in a Jewish cemetery". Howard's mother is a caricature of an over-protective Jewish mother.

Neither Leonard's nor Penny's religious convictions are made clear. Leonard approaches Christian festivals with less skepticism than Sheldon. Penny has expressed belief in ghosts, astrology, psychics and voodoo. Bernadette is Catholic, and Amy is agnostic, stating in "The Lunar Excitation" that she understands the notion of a deity but is skeptical of one that would take attendance.

Howard's mother

In many episodes, Howard has loud aggravated shouting conversations with his overprotective mother who speaks with a Brooklyn-esque accent; it's implied that she's in a different area of the house and therefore, has never appeared onscreen. She is dependent on Howard, as he is on her. The other characters frequently do impressions of her and Bernadette's is especially accurate.

Vanity card

Like all shows created by Chuck Lorre, The Big Bang Theory ends by showing a vanity card written by Lorre after the credits. These cards are archived on Lorre's website.[43]

Ratings

U.S. standard ratings

The Big Bang Theory has been highly rated since its premiere. During its fourth season, it became television's highest rated comedy, just barely beating out eight-year champ Two and a Half Men. However, in the age 14-49 demographic (the show's target age range), it was the second highest rated comedy, behind ABC's Modern Family. The fifth season opened with viewing figures of over 14 million.[44]

The Theorists controversy

Through the use of his vanity cards at the end of episodes, Lorre alleged that the program had been plagiarised by a show produced and aired in Belarus. Officially titled Теоретики (The Theorists), the show features "clones" of the main characters, a similar opening sequence, and what appears to be a very close Russian translation of the scripts.[91] Lorre expressed annoyance and described his inquiry with the Warner Brothers legal department about options. The television production company and station's close relationship with the Belarus government was cited as the reason that any attempt to claim copyright infringement would be in vain because the company copying the episodes is operated by the government.[92]

However, no legal action was required to end production of the other show: as soon as the word got out that the show was unlicensed, the actors quit and the producers cancelled it.[93] Dmitriy Tankovich (who plays Leonard's counterpart, "Seva") said in an interview: "I'm upset. At first, the actors were told all legal issues were resolved. We didn't know it wasn't the case, so when the creators of The Big Bang Theory started talking about the show, I was embarrassed. I can't understand why our people first do, and then think. I consider this to be the rock bottom of my career. And I don't want to take part in a stolen show".[94]
