host. When Kilborn left the show prior to the 1999 season, Jon Stewart took over hosting duties, also serving as a writer and co-executive producer. From this point, the series gradually began to take on a more political tone and increase in popularity, particularly in the latter part of the 2000 U.S. presidential election season. The roles of the show's correspondents were expanded to include more in-studio segments and international reports, which were almost always done in the studio with the aid of a greenscreen. Unlike Stewart, who essentially hosted The Daily Show as himself, Colbert developed a correspondent character for his pieces on the series that was a parody of conservative political pundits such as Bill O'Reilly. Colbert has described his correspondent character as "a well-intentioned, poorly informed, high-status idiot" and "a fool who has spent a lot of his life playing not the fool – one who is able to cover it at least well enough to deal with the subjects that he deals with". Colbert was frequently pitted against knowledgeable interview subjects, or against Stewart in scripted exchanges, with the resultant dialogue demonstrating the character's lack of knowledge of whatever subject he is discussing. Colbert also made generous use of humorous fallacies of logic in explaining his point of view on any topic. Other Daily Show correspondents have adopted a similar style; former correspondent Rob Corddry recalls that when he and Ed Helms first joined the show's cast in 2002, they "just imitated Stephen Colbert for a year or two". Correspondent Aasif Mandvi has stated "I just decided I was going to do my best Stephen Colbert impression". Colbert appeared in several recurring segments for The Daily Show, including "Even Stevphen" with Steve Carell, in which both characters were expected to debate a selected topic but instead would unleash their anger at one another. Colbert commonly hosted "This Week in God", a report on topics in the news pertaining to religion, presented with the help of the "God Machine". Colbert filed reports from the floor of the Democratic National Convention and the Republican National Convention as a part of The Daily Show's award-winning coverage of the 2000 and 2004 U.S. presidential elections; many from the latter were included as part of their The Daily Show: Indecision 2004 DVD release. Other pieces that have been named as his signature segments include "Grouse Hunting in Shropshire", in which he
