jquery - a scripting tool. I'm not a programmer and I had scripting tools in Fortran.
adwords - an advertising tool. Altavista, Jeeves, metacrawler and others all had said same.
gmail - seriously?
maps - mapquest was first in the consumer sphere, delorme beat Gmaps by 4-5 years.
"search processor?" The google algorithm was an innovative approach but since 2001, Google has been tweaking the algorithm, not reinventing search.
I worked a meeting with a VP from Google once. He told a large multinational corporation (under NDA) that Google's modus operandi is to move into a mature area of technology and suck all the profit out of it. They're deliberately not looking for places they can innovate - they're looking for low-hanging fruit they can pluck via brute force. Google Maps, for example, beat out Mapquest because Google was willing to invest in driving.every.road.
That's not innovation. That's brute force.
