I betcha lots of marketers are asking that same question. Michelle Hammond tells us that Eric Schmidt, speaking at this year's LeWeb conference in Paris, told attendees that Google acquired about one company per week in 2011.

Hammond writes that the actual figures show Google acquired 57 companies in 2011, for an approximate total of $14 billion.
