Google co-founders step away, making Sundar Pichai Alphabet's CEO

Larry Page and Sergey Brin, the former Stanford University students who founded Google out of a Silicon Valley garage, said Tuesday they are stepping aside as leaders of the internet behemoth they started two decades ago. Page and Brin are handing over the reins to Sundar Pichai, who will take over as CEO of Google's parent company Alphabet, in addition to his current responsibilities as cheif executive of the search giant.

The announcement comes four years after Google restructured itself under an umbrella called Alphabet. As part of the move, Google's internet businesses, including its search engine and maps app, were separated from more experimental projects like driverless cars. Pichai became CEO of Google, and Page and Brin controlled Alphabet.

Now Pichai, an Indian immigrant who joined the company in 2004, is in charge of it all.
