No. Colbert was a satire show, his gimmick was based on O'Reilly, and Colbert is a comedian, his show was on Comedy Central, and he was really funny. And he used to mention a really weird news story at the beginning of his show, like this time in New York City when skyscrapers were reflecting sun rays, causing cars below to melt.
And, not like Limbaugh at all, because Colbert did have his book club that was a spin-off of Oprah's book club, and he encouraged his audience to read. He also had a bunch of scientists on his show, including Niel Degrasse Tyson and Michio Kaku; both were frequent guests of the show.
And, unlike the real TV news anchors who said they supported the troops and may, at most, have sent money to some pro-troop cause, Colbert had shows with all-military audience members, several shows in Iraq, and he had beer and hot dogs for one group of troops (which caused PETA to ***** saying he should have had vegan alternatives, which had Colbert taunting and mocking them over it), and the hot dogs were even served by Biden.
And the show was hilarious. During one February, after a story about KKK members being arrested for having someone (who was actually Jewish) build them a death ray, he had a short cartoon on his show that was about aliens invading Earth and Obama calling in a branch of the Klan to come in and save the day.
And, with that link, if you haven't watched the video yet you should. It's Obama (actually Obama) making fun of himself.
