The American Heritage Dictionary, Second College Edition, 1985Continuity (pg. 317)
"3a. A detailed shooting script consulted to avoid errors and discrepancies from shot to shot in a film.
3b. A script for all the spoken parts of a radio or television program."
Well, the latter, thank goodness, is not an issue.
Now, as for the first, this is and has been an issue for Star Trek. The issue with the fifth series is that the Executive Producer Rick Berman and his associates will ignore continuity with the first series. This issue has already occured and under the past supervision of his predecessor, Executive Producer Gene Roddenberry.
Deneb Star System
The brighest star in the constellation Cygnus, approximately 1,630 light years from Earth. (pg. 381, same source as continuity)
Star Trek
This system has two inhabited worlds and is enclosed in Federation space. The Klingon Empire is familiar with this system and its inhabitants.
Deneb 2-"I, Mudd". This civilization is either a member or a trading partner with the Federation. They have an independent space fleet and draconian laws.
Deneb 4-"Where No Man Has Gone Before". A civilization of telepaths. Starfleet officers are trained to hone their telepathic skills on this world in the early 2260's.
On either of these two worlds, or another world in this system, there lives the Denebian slime devil ("The Trouble with Tribbles").
Star Trek: The Next Generation
A star system at the edge of Federation space. Considered a good place to station a base.
Deneb 4-("Encounter at Farpoint"). This civilization has no telepaths and has had limited contact with Starfleet. They are close to Ferengi space.
This discrepancy from the first series occured when Gene Roddenberry had active participation in the Star Trek franchise.
And so, Executive Producer Berman is himself continuous in the tradition of discontinuity as established by the teacher and founder, Gene Roddenberry.
