The 1990s was the decade when Marvel Comics sold 8.1 million copies of an issue of the X-Men, saw its superstar creators form their own company, cloned Spider-Man, and went bankrupt. The 1990s was when Superman died, Batman had his back broken, and the runaway success of Neil Gaiman's Sandman led to DC Comics' Vertigo line of adult comic books. It was the decade of gimmicky covers, skimpy costumes, and mega-crossovers. But most of all, the 1990s was the decade when companies like Image, Valiant and Malibu published million-selling comic books before the industry experienced a shocking and rapid collapse.
