 As a correspondent, Colbert was regularly pitted against knowledgeable interview subjects, fellow correspondent Steve Carell, or host Jon Stewart in scripted exchanges which typically revealed the character's lack of knowledge of whatever subject he was discussing.Other "Daily Show" correspondents have since 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".In 2005, Colbert left "The Daily Show" to host a spin-off series entitled "The Colbert Report", a parody of personality-driven political pundit programs such as Fox News's "The O'Reilly Factor" that center largely on the personal views of their hosts.
