The History of Spidey
The comic was first released in anthology comic book Amazing Fantasy #15 (August 1962). Created by writer-editor Stan Lee and artist Steve Ditko (And possibly artist Jack Kirby, though he is credited in the creation of the web slinger). The story followed the nerdy but endearing teen, Peter Parker. He went to school one day, entering a lab unsafely and was bitten by a radio-active spider, granting him spider powers. Those powers included super strength, webshooting powers (from his wrists), spider-sense, an ability to stick and to climb up walls, and many more spider-like powers. It wasn't expected to do well actually, infact Spidey was an experiment.
During this age of comics it was known as the Silver Age of Comics, though they were on the decline the products were still jaw-dropping and oozed with love from their creators. The classics were born in this era. At the time comic book heros never were flawed, or a teen at that but Spider-Man was.
And it. was. a. hit.
The comics were flying off the shelf. Teens who enjoyed these comcis finally had a hero they could see themselves in. Peter made mistakes- He was flawed because he was a kid. He took the deadly mistakes and learned. More over he was tired of his life, he was a scrawny, nerdy kid (Similar to the main audience for comic books at the time) who used the Spider-Man sona as a way to escape his stressful life. He was more than relatible. It was refreshing.
And so, Marvel, seeing the great success in the teen-hero gave him his own title. During this time Spider-Man became more obviously political. He fought to go against drugs and promote safety and for kids to take on their responsiblity.
But what about Spidey? What is his story and how did he get his powers?

The Story of Spider-Man
A bite from a spider somehow granted teenager Peter Parker its arachnid abilities and instead of using them for personal gain, he decided to help others with them. An orphan living with his aunt, May Parker, the boy chose to wear a mask while fighting crime so as not to burden her with his actions.
Calling himself Spider-Man and sporting a pair of web-shooting devices he’d constructed, Parker wound up in internet videos which attracted the attention of Tony Stark. The billionaire industrialist deduced Spider-Man’s secret identity and approached Parker at his and May’s home in Queens, New York with a request for aid from the hero in an upcoming confrontation with Captain America and a group of other rogue Avengers and associates. Parker was initially hesitant to even admit his secret career as Spider-Man, but the thrill of adventure and Stark’s talk of responsibility drew him in and he accepted the invitation, as well as a new, high-tech costume and web-shooters.
