Alphabet Inc., based in Mountain View, California, is an American global technological conglomerate holding corporation. On October 2, 2015, it was formed as a result of a Google reorganization, and it became the parent company of Google and many previous google subsidiaries. The two Google co-founders remained as Alphabet's controlling owners, board members, and workers. Alphabet is the world's third-largest technological firm in terms of sales, as well as one of the most valuable. The creation of Alphabet Inc. was motivated by a desire to make Google's core business "cleaner and more responsible," while also enabling group firms that operate in industries other than Internet services more autonomy. Larry Page and Sergey Brin, the company's founders, announced their resignations from senior positions in December 2019, with Sundar Pichai, who is also the CEO of Google, taking over as CEO. Page and Brin are still co-founders of Alphabet Inc., as well as workers, board members, and controlling shareholders.
