On Monday, the tech giant said it would become a subsidiary of a new company called Alphabet. The new umbrella company will be run by Google CEO Larry Page and co-founder Sergey Brin, while Sundar Pichai will take over as Google's new CEO in the company's fourth quarter.
Pichai is currently a senior vice president in charge of Internet businesses.
