Amazon utterly revolutionized online shopping, a benefit Amazon provided. There's simply no way it could have otherwise grown to the biggest company in the world from a garage in Bellevue.

25 years later it's easy to assume that online shopping was always like it is today. No way. Nobody even conceived of what it has become. I remember, for example, when ordering by mail meant "allow 3 to 6 weeks for delivery". I'm still astonished by next day delivery - which Amazon created and made ordinary.
