(written from a Production point of view)
He became Co-Executive Producer of the series at the end of its first season but left at the end of the second season, after difficulties with Gene Roddenberry. His position as head writer was eventually assumed by his friend, Michael Piller, who joined the Star Trek staff due to Hurley's invitation. Nonetheless, Hurley would return to the series to write two more episodes, "Galaxy's Child" for season four and "Power Play" for season five.
As the writer of the episode "Q Who", Hurley was the creator of the Borg when he came up with the idea of an unbeatable foe. (TNG Season 2 DVD special feature "Departmental Briefing Year Two: Production") Alongside Rob Bowman and Bowman's assistant he also provided the Voice of the Borg for this episode. He was also partly responsible for the introduction of Lore (having co-written the story for "Datalore") and the introduction of the Romulans in the Next Generation era (he wrote the teleplay for "The Neutral Zone").
The late Herbert J. Wright cited Hurley as one of the reasons he left TNG. He described Hurley as "basically playing drinking buddies with Gene." (Captains' Logs: The Unauthorized Complete Trek Voyages, p. 224) Tracy Tormé also named Hurley as one of the causes of his departure, after numerous disagreements over Tormé's scripts. (Captains' Logs: The Unauthorized Complete Trek Voyages, pp. 170, 177-178, 181-182)
According to Rick Berman, Hurley was the reason behind Gates McFadden's departure from The Next Generation in its second season, as he disliked her acting and "had a bone to pick with her." After he left the show in the third season, McFadden was invited back by Berman.
