Bryan Fuller has stepped aside as showrunner of Star Trek: Discovery, but will remain with the series as an executive producer. He tweeted the news to fans: "Riker spent 7 years of TNG unready for Captaincy, @GretchenJBerg @AaronHarberts are ready. Thrilled to see them in command of the Bridge."
A statement from CBS Television Studios added, "We are extremely happy with the creative direction of Star Trek: Discovery and the strong foundation that Bryan Fuller has helped us create for the series. Due to Bryan’s other projects, he is no longer able to oversee the day-to-day of Star Trek, but he remains an executive producer, and will continue to map out the story arc for the entire season. Alex Kurtzman, co-creator and executive producer, along with Fuller’s producing partners and longtime collaborators, Gretchen Berg & Aaron Harberts, will also continue to oversee the show with the existing writing and producing team. Bryan is a brilliant creative talent and passionate Star Trek fan, who has helped us chart an exciting course for the series. We are all committed to seeing this vision through and look forward to premiering Star Trek: Discovery this coming May 2017.”
