An hour ago for no particularly good reason I found myself flipping through Google's S-1 and reminiscing about the good ol' days six months ago (ha!) when Google was worth less than Disney. (As of closing today, Disney at 25.12/share is worth $51.6 billion, and Google at 193.30/share is worth $52.4 billion. But I digress...)
Flipping through the S-1, I found myself wondering how many companies has Google bought? A random walk of John Battelle's Searchblog and SearchEngineWatch didn't reveal a complete list, and the purchase list from SearchingOnTheWeb has a comparison of the acquisitions made by Ask, Google, Microsoft, and Yahoo/Overture that is interesting but at least a year out of date.
Google's S-1 claims that from February 2001 through February 2003 there were four acquisitions -- though in my slacker-search of the Internet, for the life of me I can only find three (Deja, Outride, and Pyra) -- with aggregate then-value of $133,800 in stock. (Value of those shares now that GOOG is worth $52.4 billion? Priceless!)
Since February 2003, I was able to find seven more acquisitions (Applied Semantics, Kaltix, Sprinks, Ignite Logic, Neotonic, Picasa, and Keyhole) and one investment (Baidu).
Here's the summary. I tried to keep my remarks to a minimum, for some definition of the word "tried"...
between: some unnamed company? (according to the S-1)
5/2003: Iceland (ok, not really... :)
10/2003: Genius Labs (bless you, Biz Stone! :)
perhaps: Monster, Doubleclick, AOL, Disney (it is conjectured)
eventually: Microsoft (although "There are a lot of liabilities in acquiring Microsoft." :)
Update, October 29, 2004. Another look at the ten acquisitions to date -- the assets of Deja and Outride, plus Pyra, Applied Semantics, Kaltix, Sprinks, Ignite Logic, Neotonic, Picasa, and Keyhole -- reveals a common theme: these are all small, creative, engineering-driven teams with no-bullshit cultures and interesting products and/or innovative technologies. A key challenge going forward is... can Google absorb bigger companies that contribute revenues, instead of just innovative products that make the company be seen as the Keeper Of Cool Things (so more people are willing to buy ads and/or display ads).
