It did not take long for other publishers to begin using the limited series format. In 1982, Marvel Comics published its first limited series, "Marvel Super Hero Contest of Champions", followed shortly thereafter by miniseries featuring the X-Men's Wolverine and then the Avengers' "The Vision and the Scarlet Witch". At first, Marvel used the limited series format to feature popular characters from team titles and put them in solo adventures. "Contest of Champions" brought forth the idea of a major event affecting the Marvel Universe; crossovers were introduced in limited series form before the concept of multi-title crossovers was even conceived. This would be taken further with the 12-issue "Secret Wars" saga in 1984 and by DC's saga "Crisis on Infinite Earths" in 1985-1986.
