The
2010 Tonight Show conflict was a media and
public relations conflict involving American television network
NBC and two of its then-
late-night talk show hosts,
Conan O'Brien and
Jay Leno. Leno, the host of long-running franchise
The Tonight Show since 1992, and O'Brien, host of
Late Night since 1993, were strong ratings leaders for the network for much of the decade. When O'Brien's contract neared its end and he was courted by other networks in 2001, NBC extended his contract and essentially guaranteed him he would be the fifth host of
Tonight. The network neglected to let Leno know this until his contract extension in 2004, when they informed him he would remain host for five more years and then transition the show to O'Brien in 2009. When that time arrived, other networks conveyed interest in Leno; NBC, in an effort to keep both of its late-night stars, offered Leno a nightly primetime show before the local news and O'Brien
The Tonight Show.
