I'm super excited that the Spider-Man line is getting more big movie treatment again, and that new movies will come out about him. He's my favorite superhero. I think writer/editor Stan Lee and writer/artist Steve Ditko did an amazing job conceiving him.
When did Spider-Man first come out?
He started poking around in 1962, so he's been around a long, long time. Came around in the anthology comic book "Amazing Fantasy" #15, i nthe Silver Age of Comic Books. 
That is quite a long time, is he considered a Marvel character or something else?
raised by his Aunt May and Uncle Ben in New York City after his parents Richard and Mary Parker were killed in a plane crash. Lee and Ditko had the character deal with the struggles of adolescence and financial issues, and accompanied him with many supporting characters, such as J. Jonah Jameson, Harry Osborn, Max Modell, romantic interests Gwen Stacy and Mary Jane Watson, and foes such as Doctor Octopus, Green Goblin and Venom. His origin story has him acquiring spider-related abilities after a bite from a radioactive spider
