Google changed its corporate structure in 2015 so that Alphabet Inc. became its parent company.
The restructuring separated Google’s core internet products from several other businesses and projects. Sundar Pichai became Google’s chief executive, while co-founders Larry Page and Sergey Brin led Alphabet as chief executive and president, respectively. Google remained the best-known operating company inside the new holding structure.
Alphabet is a major market-capitalization company because its businesses include Google Search, YouTube, Android, Google Cloud, and advertising technology. The change did not mean the familiar Google products disappeared or that Google became Alphabet in everyday branding. It primarily clarified reporting lines and allowed distinct ventures, such as Waymo, to operate under the parent company.
