Earlier quoted context omitted.
Google does not get the credit for making the Internet searchable; there were some pretty decent search engines, like AltaVista, before Google came along. Google made an incremental improvement in search algorithms and figured out how to make search very profitable.
I think you're wrong there. I remember using the web back then. Search sucked before Google. Altavista was a bit better than what came before it, but Google really was the first search engine that was any bloody good at all . The PageRank algorithm basically cracked the search problem. Making money actually came years later. Google used the method of "get a zillion users and we'll figure out money later."
A huge data set mapping the search terms -> clicks is what made all the difference IMO.
