(written from a Production point of view)
After Trek was a companion show to the first season of Star Trek: Discovery, which aired on CBS All Access, and first premiered in September 2017. It was hosted by Matt Mira and produced by Embassy Row in association with Roddenberry Entertainment. It was the first companion Star Trek series and the first Star Trek series to not be set in the Star Trek universe.
A post-episode discussion series with no predetermined run time, in the vein of Talking Dead, another Embassy Row production, the show aired immediately after the debut of each episode of Discovery on CBS All Access. Each episode was also made available as an on-demand release shortly after its initial airing.
The show's format incorporated interactive elements which allowed viewers to communicate in real-time with the host and his guests, through online polls and social media.  One segment of each show was entitled "Cadet Training" and focused on past Star Trek episodes that resonated with the most recent installments of Discovery.
Although it was originally stated that the series would be "retooled" for Discovery's second season,  it was announced on 17 January 2019 that the series had been discontinued, to be replaced by weekly streams on Facebook Live,  and which became the significantly scaled-down The Ready Room. 
- The series was announced on 17 May 2017 during the "CBS Upfront" media presentation and bore the working title of "Talking Trek".  The final revised title was revealed in a trailer on 21 September 2017,  and Mira was announced as the show's host on the following day. 
- Throughout the series, a variety of different Star Trek memorabilia and merchandise was featured on the shelving behind the host, with slight variations seen between episodes. Among the items displayed were tribbles, Starfleet insignia, a Klingon blade weapon, a phaser, USS Enterprise and Klingon Bird of Prey Owners' Workshop Manuals, a Vulcan IDIC, and prototypes of both the USS Shenzhou and USS Discovery models from the Star Trek: Discovery The Official Starships Collection partwork, at the time yet to be released commercially.
