NEW YORK — Turner says TBS has closed a new deal with Conan O’Brien that extends through 2022.

TBS and sister Turner network TNT plan to launch a total of six new series from stars such as Snoop Dogg, Daniel Radcliffe and Michael Moore. And TNT is working with filmmaker Ridley Scott to develop original science-fiction programming.

Talk-show veteran O’Brien’s new four-year pact with TBS keeps him at the network where “Conan” debuted in November 2010 after his abrupt exit from “The Tonight Show” when NBC reinstated Jay Leno.

But the format and distribution strategy for O’Brien’s talents will evolve from his current Monday-through-Thursday hour. He will “expand the boundaries from a talk show to a range of personality-based, cross-platform experiences,” according to TBS.

Plans call for extending his brand into digital content, podcasting, gaming, pay TV and live events.

With Ridley Scott (“The Martian,” “Alien: Covenant”), TNT will develop an evening-long programming block of original science fiction in many forms, serving as a showcase for hour-long series, short form and other formats.

In late fall, TNT will debut “Michael Moore Live from the Apocalypse,” a nonfiction series from the Oscar-winning filmmaker that promises to blow the whistle on everything from Washington politics to Wall Street shenanigans. Moore will star in the series as well as direct and produce.
