Alphabet became the parent company of Google when the new corporate structure was created in 2015.
Google announced the Alphabet reorganization in August 2015, and the new holding company became effective later that year. Larry Page became Alphabet’s chief executive, while Sundar Pichai became Google’s CEO. Google remained the largest business within Alphabet, focusing on products such as Search, YouTube, Android, and advertising.
The structure separated Google’s core internet operations from other ventures, including life sciences and research projects. Alphabet’s companies have included businesses connected with autonomous driving, health technology, and venture investing, although particular subsidiaries and reporting structures can change over time.
Alphabet is the listed corporation whose shares trade under the Google-era stock classes. A frequent mistake is calling Alphabet simply “the new name for Google.” Google was reorganized as a subsidiary, not eliminated.
