Nellie Andreeva, writing for Deadline: Star Trek: Discovery will debut Sunday, September 24, with a special broadcast premiere on the CBS TV network airing 8:30-9:30 PM. The first as well as the second episode of the sci-fi series will be available on-demand on CBS All Access immediately following the broadcast premiere, with subsequent new episodes released on All Access each Sunday. Originally slated for a January 2017 premiere, Star Trek: Discovery's debut was first pushed to May and then to fall 2017. At CBS' upfront presentation, the company announced that Star Trek: Discovery's first-season order had been increased from 13 to 15 episodes. The expanded season now will be split into two. The first eight episodes will run Sundays from September 24 through November 5. The season then will resume with the second chapter in January 2018. The break also will allow the show more time for postproduction on latter episodes.
