It all started with Showcase #4, starring  The
   Flash. This Flash was a revamped version of the Golden Age Flash, he was created by Julius Schwartz and Carmine Infantino. After a few appearances in Showcase comics, The Flash received
   his own title. The success of The Flash caused other golden-age heroes to
   come back, although revamped like The Flash. In short, The Flash became a hero
   on two fronts, first in the comic book, and second in the comic industry.
   Bringing back The Flash brought superheroes back into the mainstream, and
   changed the comic industry to this day. This includes other superhero 
   comic books, their T.V. shows, movies, and anything else they might have
   inspired.
It should also be mentioned that in 1955 a small story in the back of
   Detective Comics #225, starred an alien known as J'onn J'onzz. This
   alien would later become known as the Martian Manhunter, a major hero
   in the DC universe.
In 1958, a very important thing happened to Marvel Comics in Strange Worlds #1. This comic book was the first book put out by Stan Lee and Jack Kirby. These two individuals, along with several other artists, started doing superheroes for Marvel Comics and created what is known as the "Marvel Age".
The Marvel Age started in 1961, when Marvel Comics started to put out it's
   own superheroes. The very first superhero book that Marvel produced was
   Amazing Adventures #1 which had a character named Dr. Droom (not 'Doom').
   This character didn't work out so well, but Marvel did keep putting out other superheroes. Dr. Droom was later revamped and brought back as Dr. Druid.
The very first superhero team book Marvel put out was Fantastic Four #1,
   which also came out in 1961. In DC all the characters in a team got along
   just fine and there were no problems between them. But not in this book! A
   particular member of the Fantastic Four was Ben Grimm, A.K.A. The Thing.
   This character has a horror-style feel to him. He truly was his name, a thing, a
   monster who scared people when they looked at him.
The Thing did not get along with other members of his group, he would often
   get angry at them and fight them. He's gone through several bouts of
   depression because of the way he looks. Ben Grimm made the comic book seem
   real. This was a guy whose superpowers came with a terrible side
   effect and he wasn't happy about it. He wasn't the cheery rosy happy
   superhero that you kept reading about at DC. Another character that had a horror-
   style beginning was The Hulk, who was also a monster.
 
The Fantastic Four comics were labled "The Worlds Greatest Comic Magazine".
   It's a brave title, but one they lived up to. The Fantastic Four comic made many changes to the 
   comic industry. Much of them was with their outerspace stories, but some of them were right at home on earth.
   One of them was allowing heroes to get married. In the Fantastic Four Annual #3 (1965),
   two of the main characters, Reed Richards and Susan Storm got married. This was a big 
   change from the times when the hero wouldn't even kiss the girl. But they went further than that. 3 years later Reed and Sue had 
   a baby. In Fantastic Four Annual #6 (1968) Franklin Richards was born. Through out the comic, and 
   even today, we see this Superhero team have to go through the unique troubles of raising a superpowered 
   child while living a life of adventure.
In Flash #123, put out in 1962, both the Golden Age and the Silver Age 
   Flash appeared in the same comic. It would be the first time a 
   Golden and a Silver Age version of the same hero would meet. It would 
   also be very confusing. In the early Silver Age Flash comics, they would 
   show a young Barry Allen reading comic books that were our Golden Age 
   comic books. The Golden Age Flash was a fictional character in 
   the Silver Age. So how did they meet? This is when DC came up with the
   idea of parallel worlds. They explained that the Golden Age Flash 
   was a real person on Earth-2, and by crossing over, the two could appear 
   at the same time. This Earth-2 where Golden Age superheroes really existed was soon used
   to bring back other Golden Age superheroes like the Green Lantern 
   and many others. At the same time DC brought in other heroes that existed
   in other "Earths" where there were no other heroes. Over time this all 
   got very confusing, and DC tried to fix it in 1985 with a Crisis of 
   the Infinite Earths mini series. You'll learn more about that later.
The most well-known superhero that Marvel would produce would first
   appear in Amazing Fantasy #15. This was Spider-Man. Like 
   Captain Marvel before him, Spider-Man was a youth who kids 
   could relate too. Peter Parker was considered a geek at school, 
   he had a hard time getting dates, and bullies picked on him. Peter
   remained someone readers could easily relate to as he grew older. He had 
   a crabby boss named James Jonah Jameson, and sometimes had
   troubles with landlords when it came to paying rent.
Stan Lee and Jack Kirby created over 90% of the superheroes in the
   Marvel Comics Universe. Most of them are still around today. They also
   created superhero teams like The Avengers and their current most successful
   team are The X-men. It would take forever to list all the heroes that
   they created. Another dramatic change they made to comics was giving their villains superpowers,
   too. Before this time, heroes usually fought aliens, mad scientists, robots, thieves,
   gangsters, and people from the future. But it was rare when a villian had superpowers like the
   heroes. Now they did on a regular basis, and in doing so comic books became more interesting
   and fun to read. During the Silver Age there were some titles that brought in a lot of 
superheroes and superhero teams. Click here to read about 
them 
 The X-men were a different group of heroes. They were not gods from other
   worlds, or scientists that were caught in a lab experiment gone wrong. They
   were people just like everyone else, who happened to be born with an extra
   ability or ablities. But all was not rosy for them, because these "mutants" were the
   next step in our evolution and had powers that society didn't
   understand. The result of this was society hated and feared them.
   Doing this showed parallels to racism and also showed why racism is wrong.
   Today The X-Men are the most popular superhero team in comic books. It should be said that Marvel's X-Men is not the first comic book to do this.
   A DC hero named Aquaman also gave a message against racism, by showing
   how he was treated badly as a baby for having yellow hair. It was believed
   by the Atlantians (an underwater race of people) that those with yellow
   hair were sons of the devil. 
 During the Marvel Age, Marvel Comics revived some of their Golden Age
   heroes, others they revamped. In Fantastic Four #4 we saw the return of
   Namor the Sub-Mariner. In Avengers #4 we saw the return of the original
   Captain America and in X-Men #10 we saw Ka-Zar again. 
 In 1966, The first main black superhero that Marvel put out was the Black
   Panther in Fantastic Four #52. Although he did not have a long time running
   series, he did start a wave of black superheroes. Some of the others to
   come out after him would be The Falcon, Power Man (Luke Cage, hero for hire),
   DC's Black Lightning, and Image's Spawn. (You will learn about the Image
   company later). The Black Panther did have his own title from 1977 to 1979.
   He has also been a member of the superhero team The Avengers.  In 1969 the very first solo Dr. Doom (reportedly the inspiration for Darth Vader) 
   story came out in Marvel Super-Heroes Presents #20. Although this book is not considered very important (or worth
   very much) it was followed six years later with the first comic book series
   that focused on a supervillain (or two in this case). In 1975 villains would
   get their own comics. Marvel's Super Villain Team-Up, starred Dr. Doom and had
   him team up with another villain in every issue. The villain focus was also
   done by DC with Batman's famous villain called The Joker. Neither of these
   would last very long, but they started a villain focus trend that is still
   happening today. Sometimes the supervillain comics are just a limited series, sometimes
   an ongoing series.
