Acquired for: $50 Million

Everyone’s heard the story of Google M&A chief David Lawee calling Android the company’s “best deal ever.” That’s up for debate. However, there’s no denying the merger's significant impact on the mobile industry. Since its official coming out party in October 2008 with the T-Mobile G1, Google's OS has gone on to capture more than half of the mobile market share (54 percent at the moment) and continues to grow on a global scale with over 1 million device activations per day. Though Google’s only banked $500 million since the platform’s launch, its ginormous user base, plus mobile search and advertising solutions should hopefully make it a more profitable acquisition in the next few years.
