A few years ago, we spoke of the "AdSense Economy." It was so simple. Create a website, slap on an AdSense widget, and voila: "Insta-biz." Wow! Who knew business could be so simple? AdSense was proof of Google's genius, having grown into a multi-billion dollar business in only a few years after its launch in 2003. Google's search business continues to grow in dominance, and the company's apps business is putting a serious dent in Microsoft's franchise.
