Shopping online was not so commonplace back to 1990. Jeff Bezos was clearly an optimist because he gave up his career in New York and set up a website called Amazon.com to sell books from his garage.
Bezos decided to make his website more user-friendly by adding a feature that allowed customers to write reviews about books thay had bought and read.
That was considered to be the starting point of massive orders and Amazon.com was soon selling 100 books per day.
Got anything to add?
