Alphabet Inc

Alphabet Inc. is an American multinational conglomerate headquartered in Mountain View, California. It was created through a corporate restructuring of Google on October 2, 2015, and became the parent company of Google and several former Google subsidiaries. 

The establishment of Alphabet was prompted by a desire to make the core Google internet services business "cleaner and more accountable" while allowing greater autonomy to group companies that operate in businesses other than Internet services.
