Situation Comedy

　　A sitcom or situation comedy is a genre of comedy performance originally devised for radio but today typically found on television. Sitcoms usually consist of recurring characters in a format in which there are one or more humorous story lines centred on a common environment, such as a family home or workplace.The situation comedy format seems to have originated in the old time radio era of the United States, but today they are produced around the globe. Many countries, such as Britain, have embraced the form and so sitcoms have become among the most popular programmes on the schedule.history,The situation comedy format originated on radio in the 1920s. The first situation comedy is often said to be Sam and Henry which debuted on the Chicago, Illinois clear-channel station WGN in 1926, and was partially inspired by the notion of bringing the mix of humor and continuity found in comic strips to the young medium of radio. The first network situation comedy was Amos & Andy which debuted on CBS in 1928, and was one of the most popular sitcoms through the 1930s.Situation comedies have been a part of the landscape of broadcast television since its early days. The first was probably Mary Kay and Johnny, a fifteen minute sitcom which debuted on the DuMont Television Network in November of 1947.This type of entertainment seemed to originate in the United States, which continues to be a leading producer of the genre, but soon spread to other nations.Characteristics Traditionally, situation comedies were largely self-contained, in that the characters themselves remained largely static and events in the sitcom resolved themselves by the conclusion of the show. One example of this is the animated situation comedy The Simpsons, where the characteristics of animation has rendered the characters unchanging in appearance forever?although the characters in the show have sometimes made knowing references to this. Other sitcoms, though, use greater or lesser elements of ongoing storylines: Friends, a hugely popular US sitcom of the 1990s, contains soap opera elements such as regularly resorting to an end-of-season cliffhanger, and has gradually developed the relationships of the characters. Other sitcoms have veered into social commentary. Examples of these are sitcoms by Norman Lear including All in the Family and Maude in the US, and the controversial Till Death Us Do Part in Britain.

　　Most contemporary situation comedies are filmed with a multicamera setup in front of a live audience, then edited and broadcast days or weeks later. This practice has not always been universal, however, especially prior to the 1970s when it became more common. Some comedies, such as M*A*S*H, were not filmed before a studio audience
