The 2010 Tonight Show conflict was a media and public relations conflict involving the American television network NBC and two of its late-night talk show hosts, Conan O'Brien and Jay Leno, over the timeslot and hosting duties of the long-running franchise The Tonight Show.
Leno, the host of The Tonight Show since 1992, and O'Brien, host of Late Night since 1993, were strong ratings leaders for NBC for much of the decade. In 2001, when O'Brien's contract neared its end and he was courted by other networks, NBC agreed to extend his contract and eventually make him the fifth host of The Tonight Show. The network neglected to tell Leno about this arrangement until 2004, when they informed him that O'Brien would take over as host in five years. When that time arrived, in 2009, NBC tried to keep both of its late-night stars by offering Leno a nightly primetime show before the local news and O'Brien's Tonight Show.
The Tonight Show with Conan O'Brien and The Jay Leno Show did not immediately receive strong ratings, and NBC affiliates complained of declining viewership. NBC Universal CEO Jeff Zucker, alongside NBC chairman Jeff Gaspin and executive Rick Ludwin, created a remedy: return Leno to his 11:35 p.m. ET start time and bump O'Brien a half-hour later, to 12:05 a.m. ET. O'Brien and his staff were disappointed and furious; when it became clear O'Brien would not agree to the proposed changes, the situation grew heated. Though not a breach of either host's contract, the change resulted in a public outcry and public demonstrations largely in support of O'Brien.
O'Brien's public statement that he would not participate in the "destruction" of The Tonight Show led to negotiations with NBC for a settlement. O'Brien and his staff received US$45 million (equivalent to about $63 million in 2023) to walk away from the network, with his final Tonight Show airing January 22, 2010; Leno was reinstated as host that March, while after a contractual seven-month ban against appearing on television, O'Brien moved to TBS to host Conan. Leno returned to hosting The Tonight Show from 2010 until his retirement in 2014. The controversy surrounding the scheduling move and the reinstatement of Leno was described by media outlets as "embarrassing" and a "public relations disaster" for NBC.[1][2]
