Everything changed in 1961, when Stan Lee and artist Jack Kirby ushered in "The Marvel Age of Comics" by creating "The Fantastic Four" which brought a new style of superhero comic that focused on the characters' internal drama as well as their heroic adventures. The style was a huge success, and the Lee/Kirby team went on to create the Incredible Hulk, Iron Man, the Mighty Thor, the X-Men, the Avengers, and the Inhumans. The prolific Lee worked with artist Steve Ditko to create Marvel's greatest success story, Spider-Man. Stan Lee's Marvel revolution extended beyond the characters and storylines to the way in which comic books engaged the readership and built a sense of community between fans and creators.
