Marvel seemed to really miss the mark with this one. I think fans were hoping/ expecting something along the lines of DOCTOR WHO MAGAZINE: a text-centric magazine dedicated to the still-in-production TV show with a comic strip element. Ironically, just the mix and formula that Titan Magazines followed when they launched their own TREK magazine a few years later (a formula also successfully applied to their STAR WARS and BABYLON FIVE magazines amongst others).
But Marvel chased a younger audience with an undemanding line-up of reprinted DC comics material (beginning with reprints of the six issue limited series, largely produced before the show had even started shooting) backed-up by text features lifted from Starlog's Official Magazine (Marvel didn't even change the page layouts, they just ran them as-is).
Older fans with access to a local comic book store - and eager for anything TNG prior to the show's UK TV debut - would have already been familiar with both. Marvel's only new contributions: a contents page, a letters page and some truly dire covers (I'll do a cover gallery soon).
After twenty-odd issues Marvel pulled their favoured trick of cutting the frequency to monthly in an attempt to stabilise sales and make the economics work (see also: DOCTOR WHO, FUTURE TENSE, RAMPAGE and OVERKILL amongst others). The relaunch, pitched at more "serious" fans boasted better cover designs (including a new logo), a more appealing balance of text features and comic strip and more UK-originated text features.
The reboot was an improvement but, by that point, the damage was done and ST:TNG was squeezed out by superior coverage in British magazines like TV ZONE, STARBURST and DWB and imports like the Official Magazine and STARLOG itself (which seemed to have unlimited on-set access and at least one TNG feature per issue).
