Colbert's work as a correspondent on Comedy Central's news-parody series "The Daily Show" gained him wide recognition. In 2005, he left "The Daily Show" to host "The Colbert Report". Following "The Daily Show"s news-parody concept, "The Colbert Report" was a parody of personality-driven political opinion shows including "The O'Reilly Factor", in which he portrayed a caricatured version of conservative political pundits. The series became one of Comedy Central's highest-rated series, earning Colbert an invitation to perform as featured entertainer at the White House Correspondents' Association Dinner in 2006, which he did in character. After ending "The Colbert Report", he was hired in 2015 to succeed retiring David Letterman as host of the "Late Show" on CBS. He hosted the 69th Primetime Emmy Awards in September 2017.
