Friends is an American sitcom created by David Crane and Marta Kauffman, which aired on NBC from September 22, 1994 to May 6, 2004. The series revolves around a group of friends in the New York City borough of Manhattan. The series was produced by Bright/Kauffman/Crane Productions, in association with Warner Bros. Television. The original executive producers were Crane, Kauffman, and Kevin S. Bright, with numerous others being promoted in later seasons. Kauffman and Crane began developing Friends under the title Insomnia Cafe in November/December 1993. They presented the idea to Bright, with whom they had previously worked, and together they pitched a seven-page treatment of the series to NBC. After several script rewrites and changes, including a second title change to Friends Like Us, the series was finally named Friends and premiered on NBC's coveted Thursday 8:30 pm timeslot. Filming for the series took place at Warner Bros. Studios in Burbank, California in front of a live studio audience. The series finale, airing on May 6, 2004, was watched by 52.5 million American viewers, making it the fourth most watched series finale in television history and the most watched episode of the decade.
