 After decades of stupid pet tricks, is it time for some truthiness? I'm Michael Shane and this is 90 Seconds on the Verge. 2015 for the love of god. In fact, Paul and I will be wrapping things up and taking a hike. And with that, David Letterman has officially announced the beginning of the end to his late night tenure. Letterman began CBS's The Late Show in 1993 following a high-profile breakup with NBC. David Letterman's planned retirement in 2015 is of course still a ways off, but that hasn't stopped pretty much everyone from speculating about his replacement. Deadline founder Nikki Fink says that Stephen Colbert is quote, the only one on the air currently that CBS is considering, and Mashable reports that Colbert would be willing to take the gig. According to the Hollywood Reporter, former Daily Show correspondent John Oliver was approached about taking the 1230 slot. Oliver ultimately went to HBO. As for Craig Ferguson, who currently hosts CBS's Late Late Show at 1230, multiple sources tell the Hollywood Reporter he's not a serious contender. CBS could just scrap both The Late Show and Ferguson's Late Late Show altogether and start with a clean, younger slate. Both shows are owned not by CBS, but rather World Wide Pants, David Letterman's production company. And before you ask, Jay Leno already said no.

Airing every other Tuesday night at 435 a.m. Eastern Standard Time.
