Stephen Colbert's TV show, The Colbert Report, came to an end on Thursday night (December 18th) on Comedy Central in epic fashion. An impressive amount of celebrities showed up to share their support for Colbert and give him a send off with a special song. You can check out the video above. 

Colbert was revealed to be the successor for Letterman and the "Late Show" earlier this year. Now, we know that he will take over on CBS in May 2015. 

Colbert began The Colbert Report in 2005 when he left the The Daily Show to host a spin-off series, The Colbert Report. Following The Daily Show ' s news-parody concept, The Colbert Report is a parody of personality-driven political opinion shows such as The O'Reilly Factor. Since its debut, the series has established itself as 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. 

CBS has announced that the "Late Show with David Letterman' will officially air its final episode on May 20, 2015. The 67-year-old host has been hosting the show on CBS for 22 years, winning nine Emmy awards. Before that he hosted "Late Night with David Letterman" on NBC for 11 years. 

"David Letterman has given to all of us a remarkable legacy of achievement and creative brilliance that will never be forgotten," CBS Corp President and CEO Leslie Moonves said in today's announcement. "It's going to be tough to say goodbye, but I know we will all cherish the shows leading up to Dave's final broadcast in May."

Letterman broke the news to his "Late Show" audience at earlier this year sharing, "The man who owns this network, Leslie Moonves, he and I have had a relationship for years and years and years, and we have had this conversation in the past, and we agreed that we would work together on this circumstance and the timing of this circumstance. And I phoned him just before the program, and I said 'Leslie, it's been great, you've been great, and the network has been great, but I'm retiring." 

Letterman continued, "I just want to reiterate my thanks for the support from the network, all of the people who have worked here, all of the people in the theater, all the people on the staff, everybody at home, thank you very much. What this means now is that Paul and I can be married. We don't have the timetable for this precisely down - I think it will be at least a year or so, but sometime in the not-too-distant future, 2015 for the love of God, in fact, Paul and I will be wrapping things up and taking a hike." When his remarks were over, he received a standing ovation from the Ed Sullivan Theater audience. 

Colbert has been nominated for over twenty Primetime Emmy Awards, winning six, and has won two Grammy Awards and two Peabody Awards. He was named one of Time ' s 100 most influential people in 2006 and 2012. His book I Am America (And So Can You!) was number one on The New York Times Best Seller list.
