Amazon
The biggest online retailer in the world is called Amazon.com and started in 1994 when Jeff Bezos wanted to get into the world of internet where you could make money without having to buy anything.
The man started out with books and was selling many tittle while other stores where confronting with the lack of actual books.
Giving people what they wanted, with no actual stock, just buying an reselling books, made a profit for the Amazon CEO barely in 2001, when he proved that online vendors could easily revolutionize the world offering the public the chance to buy from the comfort of their home.
Revolutionizing e-commerce and taking it to other types of products was Bezos next step, making him now one of the wealthiest men on the planet with a net worth of $40 billion.
