(written from a Production point of view)
Launched on 28 October 2014 in the United States, the service – operated by CBS Interactive – expanded to Canada on 23 April 2018 and plans to expand into Australia in late 2018 (although, due to existing rights agreements, not all of the service's programming accompany the expansion).  
In November 2015, CBS Corporation President and CEO Leslie Moonves revealed that, as a result of the various Star Trek series performing "exceedingly well" on CBS All Access, Star Trek: Discovery would premiere exclusively on All Access as the service's first original series (although The Good Fight ultimately aired first). Moonves characterized the decision as a means to entice "millions" of new subscribers.  When Discovery premiered on the service in September 2017, "record-breaking" single-day signups were reported,  though viewership numbers have never been formally disclosed, then or anytime later. The first Discovery companion series, After Trek, also aired on the service, as does Star Trek: Short Treks, Star Trek: Picard, and the second season of The Ready Room, the follow-up to After Trek. Three upcoming Trek series, Star Trek: Lower Decks, the Untitled Section 31 series and Star Trek: Strange New Worlds, will air on the service as well.  
Besides the various Star Trek productions and The Good Fight, CBS All Access original programming includes No Activity, Strange Angel, One Dollar, and Tell Me a Story (starring Kim Cattrall).
Besides original programming, CBS All Access also streams the annual Grammy Awards and games of the National Football League (NFL).
