Meet the Press is a weekly American television news/interview program airing on NBC. It is the longest-running television series in American broadcasting history, despite bearing little resemblance to the original format of the program seen in its television debut on November 6, 1947. Meet the Press is the highest-rated of the American television Sunday morning talk shows. It has been hosted by 11 moderators, beginning with Martha Rountree.

Late Night with David Letterman is a nightly hour-long comedy talk show on NBC that was created and hosted by David Letterman. It premiered in 1982 as the first incarnation of the Late Night franchise and went off the air in 1993, after Letterman left NBC and moved to Late Show on CBS. Late Night with Conan O'Brien then filled the time slot. As of March 2, 2009, the slot has been filled by Late Night with Jimmy Fallon. It will be filled by Seth Meyers in the spring of 2014, after Fallon becomes host of The Tonight Show.

Stepping into the late-late slot vacated by David Letterman, Conan O'Brien stars in a show that far outdoes its competition in sheer strangeness. Along with the celebrity interviews and musical numbers typical of late-night talk shows, this program make frequent use of odd walk-on characters and frequent "visits" from celebrity guests.
