When Spider-Man first saw print in the 1960s, teenage characters in superhero comic books were usually sidekicks. The Spider-Man series broke ground by featuring a hero who himself was an adolescent, to whose "self-obsessions with rejection, inadequacy, and loneliness" young readers could relate. Spider-Man has since appeared in various media including several animated and live-action television series, syndicated newspaper comic strips and two highly successful films, with a third set to debut on May 4, 2007.
Marvel has published several Spider-Man comic book series, the first being The Amazing Spider-Man. Over the years, the Peter Parker character has developed from shy high school student to troubled college student to married professional.
