Marvel Comics
The shared storytelling universe known as the Marvel Universe was unveiled in 1961, when Goodman responded to the growing interest in superhero books by commissioning writer Stan Lee and artist Jack Kirby to create the Fantastic Four. With the release of Fantastic Four no. 1 (November 1961), readers were introduced to a super heroic setting that was, nevertheless, rooted in the real world. Lee and Kirby tried to make their comic book characters more original by allowing them to interact with each other in a realistic fashion, including heroes often fighting or arguing with each other. This trend continued with a flood of other superhero characters introduced by Marvel Comics during the early 1960s, including Spider-Man, the Incredible Hulk, the X-Men and the Fantastic Four. Lee wrote the majority of Marvel’s books during that time, and Jack Kirby and Steve Ditko were the most important and influential artists.
