David Letterman is preparing to return to television in his first continuing series since stepping down as the host of CBS’s “Late Show” in 2015.

Netflix announced on Tuesday that it had picked up a new show from Mr. Letterman, the comedian and broadcaster.

Each hourlong episode of the series, which will run for six episodes next year, will feature a long-form interview between Mr. Letterman and a guest, as well as segments in which he explores the wider world.

Mr. Letterman said on Tuesday in a phone interview that ever since he signed off from his “Late Show” duties, “Everybody would come to me and say, ‘What do you want to do?’ And I kept saying, ‘Well, jeez, I did what I wanted to do.’”
