Google offers a ridiculous number of online services. There's the flagship Google search engine, Gmail, Google Maps, Google Earth, Google News, Google Talk, Google Docs and Google Calendar, just to scratch the surface. Then there are popular Google-owned Web sites like YouTube, Picasa and Blogger. All of these services are absolutely free.

In 2008, Google made nearly $22 billion [source: Google]. Ninety-seven percent of the company's revenue came from advertising. How did they pull this off? Google has developed two highly profitable advertising models: Google AdWords and Google AdSense.
