92nd Street Y Presents Senator Al Franken In Conversation With David LettermanDavid Letterman is returning to television — on Netflix.

The veteran host and comedian will headline a new, six-episode interview show, which the streaming service says will combine "two interests for which he is renowned: in-depth conversations with extraordinary people, and in-the-field segments expressing his curiosity and humor."

Each hour-long episode will feature longform conversations with a single guest, as well as segments in which Letterman explores the outer world. The series, as yet untitled, is expected to debut in 2018.

"I feel excited and lucky to be working on this project for Netflix," Letterman said in a statement. "Here's what I have learned, if you retire to spend more time with your family, check with your family first. Thanks for watching, drive safely."

Letterman retired from CBS' "The Late Show" in 2015. By then, he'd hosted a late night show for 33 years, including his tenure with "Late Night" on NBC. In his retirement, the host has kept a low profile.

The terms of his deal with Netflix are unknown, but it's likely the streaming service shelled out big bucks for Letterman's return to TV. Netflix has been doubling down on comedy, poaching Jerry Seinfeld's "Comedians in Cars Getting Coffee" and greenlighting specials from big names like Chris Rock, Amy Schumer, and Dave Chappelle.
