In October 2006, Google announced that it had acquired the video-sharing site
YouTube for $1.65 billion in Google stock, and the deal was finalized on November 13, 2006. On April 13, 2007, Google reached an agreement to acquire
DoubleClick for $3.1 billion, transferring to Google valuable relationships that DoubleClick had with Web publishers and advertising agencies. The deal was approved despite anti-trust concerns raised by competitors
Microsoft and
AT&T. On August 15, 2011, Google made what was, at its time, its largest-ever acquisition to date when it announced that it would acquire
Motorola Mobility for $12.5 billion subject to approval from regulators in the United States and Europe. This purchase was made in part to help Google gain Motorola's considerable patent portfolio on mobile phones and wireless technologies, to help protect Google in its ongoing patent disputes with other companies, mainly
Apple and
Microsoft, and to allow it to continue to freely offer
Android. The merger was completed on May 22, 2012, after the approval of China. In June 2013, Google acquired
Waze, a $966 million deal. While Waze would remain an independent entity, its social features, such as its crowdsourced location platform, were reportedly valuable integrations between Waze and
Google Maps, Google's own mapping service. On January 26, 2014, Google announced it had agreed to acquire
DeepMind Technologies, a privately held artificial intelligence company from
London. DeepMind describes itself as having the ability to combine the best techniques from machine learning and systems neuroscience to build general-purpose learning algorithms. DeepMind's first commercial applications were used in simulations, e-commerce and games. it was reported that DeepMind had roughly 75 employees. Technology news website
Recode reported that the company was purchased for $400 million though it was not disclosed where the information came from. A Google spokesman would not comment on the price. The purchase of DeepMind aids in Google's recent growth in the artificial intelligence and robotics community. == List of mergers and acquisitions ==
