In 99/2000 Google wasn't the massive success it was about 2 years later. And its IPO didn't happen until much later after the .com crash. It was known and popular among techies but wasn't the household name it became about 2002, 2003.
When I think of the .com crash (and I lived through it) I think of the companies that had IPOd or were about to, and took massive investment in 99. In 99 Google was still a small concern.
Amazon, yeah, I'd say Amazon is a late 90s company. Though they were just about books then.
