(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 characterised 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 figures were not divulged.  The Discovery companion series, After Trek, is also released on the service, as well as Star Trek: Short Treks and the upcoming Untitled Picard series, Star Trek: Lower Decks, and Untitled Section 31 series.  
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).
