Star Trek: Discovery is an American web television series created for CBS All Access by Bryan Fuller and Alex Kurtzman. Launched in 2017, it is the first scripted series developed specifically for that service. The seventh series in the Star Trek franchise, it was the first series in the franchise since Star Trek: Enterprise concluded in 2005. Star Trek: Discovery begins roughly a decade before the events of the original Star Trek series, and follows the crew of the USS Discovery on various adventures.
Sonequa Martin-Green stars as Michael Burnham, a female science specialist on the Discovery. Doug Jones, Shazad Latif, Anthony Rapp, Mary Wiseman, and Wilson Cruz also star, along with Jason Isaacs for the first season, Anson Mount for the second, and David Ajala for the third. The series was announced in November 2015, with Fuller acting as showrunner from February to October 2016 but leaving due to creative differences with CBS. He was replaced by Gretchen J. Berg and Aaron Harberts, who received producing support from Akiva Goldsman. Goldsman did not return after the first season, while Berg and Harberts were fired by CBS during production on the second; Kurtzman took over as showrunner, and was joined by Michelle Paradise for the third season.
Star Trek: Discovery premiered on September 19, 2017, at ArcLight Hollywood, before debuting on CBS and CBS All Access on September 24. The rest of the 15-episode first season was streamed weekly on All Access, ending in February 2018. The season's release led to record subscriptions for All Access, and positive reviews from critics who highlighted Martin-Green's performance. The 14-episode second season was released from January to April 2019, and the third season was ordered in February 2019. The series was the beginning of a wider expansion of the Star Trek franchise by CBS and Kurtzman, leading to multiple other series being produced including the direct spin-off Star Trek: Short Treks.
