Following up their various Giant-Size series from 1974, Marvel publishes a number of one-shot Giant-Size annuals featuring reprints of "classic" Captain America, Captain Marvel, Daredevil, Doctor Strange, Hulk, Invaders, Iron Man, Power Man, and Thor stories. In addition, the company publishes three Giant-Size issues (January, April, and July cover dates) of Kid Colt, and two Giant-Size issues (May and June cover dates) of the reprint title Marvel Triple Action. On the other hand, the company cancels 10 Giant-Size titles, including Giant-Size Avengers, Giant-Size Conan, Giant-Size Defenders, Giant-Size Fantastic Four, Giant-Size Man-Thing, Giant-Size Master of Kung Fu, Giant-Size Spider-Man, Giant-Size Super-Villain Team-Up, Giant-Size Werewolf, and Giant-Size X-Men.
The horror/suspense comic resurgence ends, as publishers cancel titles in droves. Marvel and its black-and-white magazines are particularly hard hit, canceling Adventure Into Fear, Dead of Night, Dracula Lives!, Giant-Size Chillers, Giant-Size Werewolf, Haunt of Horror, both Man-Thing titles, Masters of Terror, Monsters Unleashed, Supernatural Thrillers, Tales of the Zombie, Vampire Tales, and Where Monsters Dwell. DC Comics cancels Black Magic, Secrets of Haunted House, Tales of Ghost Castle, and Weird Mystery Tales. Gold Key Comics cancels Mystery Comics Digest, and Archie Comics even cancels their title Red Circle Sorcery.
