David Letterman

Much as 2014 shook the late night landscape with Jimmy Fallon's ascension to the 'Tonight Show' throne, 2015 will similarly upend the 'Late Show' as 'Colbert Report' host Stephen Colbert takes over for the retiring David Letterman. Colbert himself stopped by Letterman's couch today to talk about the transition, the first footage of which has made its way online!

Where last year we were watching David Letterman and Jay Leno still battling it out for late-night ratings, the future looks very different now that 'The Colbert Report' star Stephen Colbert has officially been announced as Letterman's replacement, to compete with the already-installed 'Tonight Show' with Jimmy Fallon.

Well, that was fast! Just one week after David Letterman dropped the 'Late Show' bombshell that he would retire in 2015, his replacement has officially been announced. Following early and decisive rumors, Stephen Colbert will officially leave behind Comedy Central's 'Colbert Report' to ascend the late-night throne as the new host of CBS' 'The Late Show.'

Lindsay Lohan hit the 'Late Show With David Letterman' last night, and the pair inevitably prank called Oprah (as one does), a gag that could have gone in a very different reaction if Winfrey wasn't so damn wise. Seriously, don't try to pull the wool over Oprah's eyes. She knows what's up.

Last week saw Dave Letterman shaking up the late-night landscape with the announcement of his imminent retirement, which as since led to all manner of speculation on a replacement, but the impact has already gone further down the pop culture rabbit hole. Watch 'The Simpsons' pay tribute to the retiring 'Late Show' leader with last night's couch gag from "Luca$"!

Yesterday afternoon David Letterman shook up the late-night landscape once more with the announcement of his 2015 retirement from 'The Late Show with David Letterman,' however inevitable the exit might have been. The internet has been awash with gossip and replacement debates since, but has 'The Colbert Report' host Stephen Colbert emerged as CBS' clear frontrunner to take the 'Late Show' throne f

During a taping of tonight's 'Late Show', host David Letterman announced to a shocked studio audience that he would be retiring in 2015 after his latest contract ends.

The late-night landscape will look drastically different by this time next year, now that Jimmy Fallon will take over for Jay Leno as host of 'The Tonight Show' in early 2014, but some things will at least stay the same. Extending his own 2014 contract, David Letterman has re-signed to stick with CBS' 'Late Show with David Letterman' through at least 2015.

To celebrate David Letterman's 20th anniversary of working on CBS, Bill Murray showed up and made quite a spectacle.

Two titans of comedy switched roles and the results were gut-busting.

A couple of nights ago, Will Smith stopped by David Letterman's 'Late Show' to promote his newest film 'After Earth.' But before he did, the one-time Fresh Prince delivered an impromptu summer jam.

Usually, getting fired can be a miserable situation. However, for A.J. Clemente, it was his ticket to fame.
