How Amazon revolutionised shopping over the last 20 years

Earlier this week, Amazon.com announced it was going to celebrate its 20th anniversary today, July 15, with what it is calling Prime Day; a 24-hour online shopping bonanza which they declared would be “filled with more deals than Black Friday”.

The event is meant as a reward to its 40 million Prime members, who each pay the equivalent of $99 to access deals on everything from books to beakers.
