The Daily Show is an American late-night talk and news satire television program. It airs each Monday through Thursday on Comedy Central. Describing itself as a fake news program, The Daily Show draws its comedy and satire from recent news stories, political figures, media organizations, and often uses self-referential humor as well. The half-hour-long show premiered on July 21, 1996, and was first hosted by Craig Kilborn until December 17, 1998.
Correspondent segments
The monologue segment is often followed by a segment featuring an exchange with a correspondent--typically introduced as the show's "senior" specialist in the subject at hand--either at the anchor desk with the host or reporting from a false location in front of a greenscreen showing stock footage. Their stated areas of expertise vary depending on the news story that is being discussed, and can range from relatively general (such as Senior Political Analyst) to absurdly specific (such as Senior Religious Registry Correspondent). The cast of correspondents is quite diverse, and many often sarcastically portray extreme stereotypes of themselves to poke fun at a news story, such as "Senior Latino Correspondent", "Senior Youth Correspondent" or "Senior Black Correspondent". They typically present absurd or humorously exaggerated takes on current events against the host's straight man.  While correspondents stated to be reporting abroad are usually performing in-studio in front of a greenscreen background, on rare occasions, cast members have recorded pieces on location. For instance, during the week of August 20, 2007, the show aired a series of segments called "Operation Silent Thunder: The Daily Show in Iraq" in which correspondent Rob Riggle reported from Iraq. In August 2008, Riggle traveled to China for a series of segments titled "Rob Riggle: Chasing the Dragon", which focused on the 2008 Beijing Olympics.  Jason Jones traveled to Iran in early June 2009 to report on the Iranian elections, and John Oliver traveled to South Africa for the series of segments "Into Africa" to report on the 2010 FIFA World Cup. In March 2012, John Oliver traveled to Gabon, on the west African coast, to report on the Gabonese government's decision to donate $2 million to UNESCO after the United States cut its funding for UNESCO earlier that year. On July 19, 2016, Roy Wood Jr. reported live from the Republican National Convention and talked about Donald Trump's African-American support.  Correspondent segments feature a rotating supporting cast, and involve the show's members travelling to different locations to file comedic reports on current news stories and conduct interviews with people related to the featured issue. Topics have varied widely; during the early years of the show they tended toward character-driven human interest stories such as Bigfoot enthusiasts. Since Stewart began hosting in 1999, the focus of the show has become more political and the field pieces have come to more closely reflect current issues and debates. Under Kilborn and the early years of Stewart, most interviewees were either unaware or not entirely aware of the comedic nature of The Daily Show. However, as the show began to gain popularity--particularly following its coverage of the 2000 and 2004 presidential elections--most of the subjects now interviewed are aware of the comedic element.
