Having fresh data on user search queries is key to a search engine’s success, lawyers for DOJ, the states and Google all agreed. Google controls the most popular browser, Chrome, and the second-most popular mobile operating system, Android.
In his presentation, DOJ’s Dintzer focused on the mechanics of Google’s search engine and how its default contracts have hemmed in potential rivals. On mobile, Google contracts with Apple, smartphone makers like Samsung and Motorola Solutions Inc., most browsers and the three US telecom carriers -- AT&T Inc., Verizon Communications Inc. and T-Mobile US Inc. -- to ensure its search engine is set as the default and comes preinstalled on new phones, Dintzer said. Microsoft’s search engine, Bing, is the default on the company’s Edge browser and Amazon’s Fire tablets, he said.
