Marvel Secret Wars in 1984 was the first major "Marvel Event". Yes, technically it was preceded by 1982's Contest Of Champions. But while "Contest" was a significant crossover, it really was only a practice run for the universe-spanning "Secret Wars".
More importantly, "Secret Wars" was the first Marvel crossover where the marketing of the event was the driving force, and the story was somewhat secondary. Marvel teamed-up with Mattel (the toy company) to create a series of plastic figures, vehicles, and play-sets. There was also a relatively restrained number of Marvel Secret Wars Color/Activity books.
The 12-part Secret Wars limited series was part of official Marvel Continuity (including the oh-so-important origin of Spider-Man's symbiotic black suit which lead to Venom, Carnage, and more). But the toys and these coloring books were completely divergent and are absolutely out of continuity.
