According to eweek, Eric Schmidt told reporters at a briefing at the Googleplex recently that Google buys a start-up once every few days, or around one a week. Usually, their business-buying strategy is to obtain either new technology or the engineers within the companies (rather than the companies themselves). Other times, it is to build out their portfolio. I have to wonder...is this unusual? Are their other companies that gobble up businesses every few days?
