From the summer of 1994: the first issue of THE FIVE TIMES, published by THE UK BABYLON FIVE FAN CLUB.
This A4 black & white first issue mainly covered the show's feature length pilot... which turned out to be pretty different to the show that followed.
From this (relatively crude) DTP start, the club and the newsletter progressed onto bigger and better things over the course of the next few years. I'm not sure they ever had the official backing of the studio (as that probably would have required a license and cash transactions) but it did have the support of the cast, crew and US fan club. Which made it all-but-official as far as I was concerned.
