In March 1980, as one of his final creations as part of his "Marvel Revolution", then editorial director of Marvel UK Dez Skinn launched the "Marvel Digest Series" pocket books line with four titles, each title containing 50 pages of black & white US Marvel reprints (making them 52 pages including covers). Using the same amount of paper as his standard weeklies, by adding an extra fold it allowed for twice as many pages to be reprinted. The line eventually included Spider-Man (also featuring at the time in his own weekly title), the Fantastic Four, Hulk, The Titans (previously a weekly title which had been cancelled some years before, now starring Captain America, Thor and Iron Man), Marvel Classics Comics (featuring adaptations of classic novels, and published twice monthly unlike the others), Conan (who also had a monthly magazine), Chiller (starring Dracula, the Man-Thing and occasionally Ghost Rider and others), Star Heroes (featuring TV tie-in Battlestar Galactica and also the Micronauts, who had transferred across from Star Wars Weekly) and Young Romance Pocket Book (featuring reprints of teenage romance titles from the fifties and sixties). Some of the titles, however, were not a success in terms of sales and Hulk, Conan, The Titans, Marvel Classics Comics and Young Romance were all cancelled after 13 issues (12 for Marvel Classics Comics), while Star Heroes (which had replaced The Micronauts with the X-Men from issue #10 following an all-Battlestar Galactica issue #9; the Micronauts resurfaced in the pages of Future Tense) was renamed 'X-Men Pocket Book' from #14, and turned solely over to the mighty mutants. Spider-Man also underwent a revamp, with the more modern stories it had started out reprinting replaced by early sixties classics after a few issues. The Spider-Man, Fantastic Four, Chiller and X-Men pocket books were all cancelled after their 28th issues in July or August 1982, with the Spider-Man strip being continued in new monthly magazine The Daredevils in January 1983 and the Fantastic Four resurfacing in their own weekly title in October 1982. Several 100 page double sized issues were produced during the various titles' runs, with the price bumped up from 15p to a then exorbitant 30p (!). The regular price would eventually rise to 25p for the four longest running titles.
