It was a Marvel comic book that released the superhero, Spiderman, to the world of comic book readers. The marvel company actually started publishing comic books in 1939, but they called themselves Timely Comics. This was the same year that many publishers tried to capitalize on the popularity of Superman and tried to reproduce its success.
The first Marvel comic book was Submariner, created by Bill Everett. This character was the first 'bad' hero that we saw in comic books and was an alien from the depths of the sea. This character still exists in comics today, but it seems to have adapted to humans. Human Torch was another of the first Marvel comic book characters and this was a completely different kind of superhero. Instead of being an alien, the torch was a machine, making it the first robot hero of comic book fame.
The comic book character that brought fame to the Marvel comic book was Captain America. Not only was this character a superhero, he was also a super soldier and in wartime, he became a very popular character fighting the German forces. This helped to inspire a country at war with Germany. Captain America was the only superhero ever to do battle with Hitler himself.
Characters introduced through the pages of a Marvel comic book include Hercules, the Falcon, the Victory Boys and the Blonde Phantom. Some of the more well-known characters including Spiderman were the Fantastic Four and the X-men. Between 1947 and 1961, Marvel released over 200 comic books. They realized that girls liked to read comic books too and started releasing comics for this section of the population. Patsy, an ordinary girl and Millie, a model, became very popular conic book characters.
It was Jack Kirby of Marvel comic book fame that invented the romantic comic book. My Date and Young Romance were immediate hits and other comic book publishers tried to imitate them. This success was only short lived and by 1951 there were no love comic books being published.
