Alphabet Inc Portfolio holdings
Alphabet is the holding company that owns Google, created in October 2015 so that Google's other businesses could run independently of its main internet products. It was set up to hold Google alongside other businesses such as Calico, Nest, Verily and Fiber, and it also includes Waymo, its self-driving car division. Google co-founder Larry Page announced the plan and ran Alphabet with fellow co-founder Sergey Brin until December 2019, when both stepped back from executive roles and Sundar Pichai, already Google's chief executive, took over as Alphabet's as well. Page and Brin remain board members and controlling shareholders. The structure follows the model of Berkshire Hathaway, a holding company whose subsidiaries are each run by a strong chief executive.
