Google to Buy Motorola Mobility for $12.5 Billion

Google announced that it will acquire Motorola Mobility for $12.5 billion in order to supercharge its Android mobile operating system and build up its patent portfolio.

The deal, Google's largest to date, puts the search king squarely in competition with Apple in mobile and living-room entertainment and cements a firm bunker to defend itself from ongoing battles with rivals over technology patents.
