Google Inc. buys Motorola Mobility Holdings Inc. for $12 billion in 2012
The Internet company primarily bought Motorola for its portfolio of 17,000 mobile patents, but Google also inherited an unprofitable division that made smartphones.

Google had previously sold a Motorola division that makes television set-top boxes to the Arris Group for $2.35 billion.
