Talk show host Conan O’Brien is joining US broadcaster TBS to host a late-night talk show that is expected to debut in November.

The comedian’s new programme will be followed by Lopez Tonight, which will shift to a midnight time slot.

O’Brien began talks in earnest with TBS just last week, after George Lopez personally called him to ask that he consider joining the network’s late-night line-up.

Lopez said, "I can’t think of anything better than doing my show with Conan as my lead-in. It’s the beginning of a new era in late-night comedy".

O’Brien says, "In three months I’ve gone from network television to Twitter to performing live in theaters, and now I’m headed to basic cable. My plan is working perfectly".

TBS has looked to build a programming slate that appeals to a young, diverse audience. It expects O’Brien to be a long-term addition to the network’s late-night landscape. O’Brien will host his hour-long, yet-to-be-titled show Mondays through Thursdays at 11 pm.

Turner Entertainment Networks president Steve Koonin says, "Conan has been the comedic voice for a generation. TBS already has a huge audience of young comedy lovers, and Conan’s show will give these fans even more reasons to watch our network".

With the addition of O’Brien’s show, TBS will establish two hours of late-night talk. Lopez Tonight, while just a few months old, has already become a destination show for a diverse audience. The Lopez Tonight audience is young as well, with a median age of just 34.

Koonin adds, "For decades, late-night TV has been dominated by broadcast television. Now, with a young audience and a growing late-night lineup, TBS is set to be the choice of comedy fans for years to come."
