I'm having a problem trying to figure out what innovative products they actually created.
EXCLUDING ANY PRODUCT OR COMPANY THAT WAS BOUGHT, what are some innovative products that Google created on it's own? Is it still alive? Is it popular?
Android(altough they bought it at first, what they bought wasn't even close to how android and touch based smartphones look today ,so it can be considered a internal development.And the innovation there was creating such OS that fits many phones and their business model with it).
Maps, I'm not so sure. Wikiepdia says it was created when Google acquired Where 2 Technologies, Keyhole, and ZipDash.
Google is double the good guy: (1) helps users for free, because advertisers pay for it (like free-to-air TV); (2) advertisers can't complain about google's high prices, because it's the other guy who bid it up (like selling munitions in an arms race).
I believe google came up with this independently BUT goto/overture did it first, patented it, sued, and google settled.
So far as revenue is concerned, this is Google's only product.
