The news comes on the same day the comedian, writer and talk show host kicks off a two-month national stage show tour in Oregon.

According to execs at TBS, which was beyond a dark horse in the intense competition to land O’Brien, the show will launch in November and will air Monday through Thursday at 11 p.m. EDT, with “Lopez Tonight” shifting to the midnight slot.

The network also revealed that serious negotiations with the floppy-haired host were relatively short-lived and only began last week.

The decision comes as a big shock to many – especially the brass at Fox, which was favored by most people speculating to be O’Brien’s new home. But, on further examination, it appears to be a pretty smart move.

Lopez has found a willing partner in TBS, allowing him room to maneuver and resulting in an edgier, more spontaneous show than many of the other late night programs he’s competing with.

Despite drawing scorn from critics like the New York Times, which called “Lopez Tonight” “a coarsening of the already crass atmosphere” of late night, the strategy has paid off for both the network and the comedian.

The show enjoyed a healthy debut in November despite low expectations, averaging 1.6 million viewers in its first week and 1.3 in its second, according to TVByTheNumbers.com.

In the months since, TBS has seen a substantial increase in its late night viewership, especially among the highly prized 18-34 and 18-49 demographics.
