Marta Kauffman in the context of "List of Friends episodes"

Friends is an American television sitcom created by David Crane and Marta Kauffman, which aired on NBC from September 22, 1994, to May 6, 2004, lasting ten seasons. With an ensemble cast starring Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer, the show revolves around six friends in their 20s and early 30s who live in Manhattan, New York City. The original executive producers were Kevin S. Bright, Kauffman, and Crane.

Kauffman and Crane began developing Friends under the working title Insomnia Cafe between November and December 1993. They presented the idea to Bright, and together they pitched a seven-page treatment of the show to NBC. After several script rewrites and changes, including title changes to Six of One and Friends Like Us, the series was finally named Friends. Filming took place at Warner Bros. Studios in Burbank, California.

Phoebe Buffay is one of the six main characters from the American television sitcom, Friends. She was created by David Crane and Marta Kauffman and portrayed by actress Lisa Kudrow.

In the series' universe, Phoebe is the daughter of Frank and Lily Buffay. Her biological mother's name was Phoebe Abbott, whom she was named after. Phoebe has a twin sister, Ursula, a waitress who is also portrayed by Kudrow. Phoebe can speak several languages, including French and Italian. She appeared in all of the show's 236 episodes during its decade-long run, from its premiere on September 22, 1994, to its finale on May 6, 2004. She is a masseuse, notable for her offbeat and often unusual behavior. She was Monica Geller's roommate before Rachel Green, which is how she was introduced to the group. Phoebe is best friends with Monica and Rachel, along with their neighbors, Chandler Bing and Joey Tribbiani, and also Monica's brother Ross Geller. She plays acoustic guitar and sings simple, awkward songs at Central Perk, occasionally busking also. During the show's ninth season, Phoebe is set up on a blind date with Mike Hannigan (played by actor Paul Rudd) and they marry in the final season.

Rachel Karen Green is a fictional character, one of the six main characters who appeared in the American sitcom Friends. Portrayed by Jennifer Aniston, the character was created by David Crane and Marta Kauffman, and appeared in all of the show's 236 episodes during its decade-long run, from its premiere on September 22, 1994, to its finale on May 6, 2004. Introduced in the show's pilot as a naïve runaway bride who reunites with her childhood best friend Monica Geller and relocates to New York City, Rachel gradually evolves from a spoiled, inexperienced "daddy's girl" into a successful businesswoman. During the show's second season, the character becomes romantically involved with Monica's brother, Ross, with whom she maintains a complicated on-off relationship throughout the series. Together, Ross and Rachel have a daughter, Emma.

The role of Rachel was originally offered to Téa Leoni, the producer's first choice, and Courteney Cox, both of whom declined, Leoni in favor of starring in the sitcom The Naked Truth, and Cox in favor of playing Rachel's best friend Monica in Friends. A virtually unknown actress at the time, who had previously starred in five short-lived sitcoms, Aniston auditioned for the role of Rachel after turning down an offer as a cast member on the sketch comedy show Saturday Night Live. After acquiring the role and before Friends aired, Aniston was temporarily at risk of being recast because she had also been involved with another sitcom, Muddling Through, at the time, which was ultimately cancelled and allowed Aniston to remain on Friends.

Monica E. Geller is a fictional character, one of the six main characters who appears on the American sitcom Friends (1994–2004). Created by David Crane and Marta Kauffman, and portrayed by actress Courteney Cox, Monica appears in all of the show's 236 episodes, from its premiere in 1994, to its finale in 2004. A chef known for her cleanliness, competitiveness and obsessive-compulsive nature, Monica is the younger sister of Ross Geller and best friend of Rachel Green, the latter of whom she invites to live with her after Rachel forsakes her own wedding. The two characters spend several years living together as roommates until Monica begins a romantic relationship with long-time neighbor and friend Chandler Bing, whom she marries. Unable to conceive children on their own, Chandler and Monica eventually adopt twins Erica and Jack and move out of their apartment into a larger house in the suburbs.

The creators' first choice for the role of Monica was comedienne Janeane Garofalo. Cox had been offered the role of Rachel but declined in favor of playing the character's best friend Monica because she was drawn to her strong personality. Meanwhile, the role of Rachel went to actress Jennifer Aniston. Before Friends aired, Monica's characterization was greatly debated among writers in regards to the character sleeping with someone on their first date during the pilot. Kauffman in particular greatly defended Monica, arguing with NBC executive Don Ohlmeyer over whether or not this would make the character too promiscuous. Ultimately, the episode aired unchanged after the studio surveyed the audience, the results of which returned in favor of Monica's existing storyline. The character's struggles with childhood obesity, challenges with romantic relationships and complicated relationship with her mother would eventually become popular staples of the show.
