Alphabet was created in 2015 when Google became a subsidiary of a new parent corporation.
Google announced the restructuring in August 2015, and Alphabet formally became the parent company on October 2 of that year. The arrangement placed Google’s core internet businesses under Alphabet while giving other ventures more independent management and reporting.
Larry Page became Alphabet’s chief executive and Sergey Brin became its president at launch. Sundar Pichai later became Google CEO in 2015 and Alphabet CEO in 2019, while Page stepped away from the executive role.
The restructuring did not split Google into separate publicly traded companies. Alphabet’s shares represent the parent group, whose market value includes Google and other operations such as autonomous-vehicle company Waymo and life-sciences venture Verily.
