This week, Yahoo (YHOO) announced that Google executive Marissa Mayer, 37, would be Yahoo's new CEO, a move that is being hailed as a"surprising coup" for the struggling internet company, which for many years has been fighting a losing battle against Google (GOOG) and Facebook (FB) for online ad dollars. Mayer was Google's 20th employee and first female engineer, and oversaw some of its most popular products, including its eponymous search engine, Gmail, Google News, Google Images, and Google Maps. Mayer is a trailblazing advocate for breaking the glass ceiling in corporate America (and also happens to be pregnant), and is widely seen as a high-profile personality who can capture the attention of the media and investors alike.

Can Mayer turn things around?

Warren Buffett once said, "The key to investing is not assessing how much an industry is going to affect society, or how much it will grow but, rather, determining the competitive advantage of any given company and how long it can maintain that advantage.

In other words, Buffett believes in investing in monopolies. While these are hard to come by, there are some companies, such as Sirius XM (XM), the only satellite radio company in the U.S., that come pretty darn close.
