Alphabet is the parent corporation created when Google reorganized under a new holding company in 2015.
Google announced the Alphabet restructuring in August 2015, and the new corporate structure became effective later that year. Alphabet placed Google’s main internet businesses alongside separately managed ventures such as research, life sciences, and other technology projects.
Google remained Alphabet’s largest operating company, housing products including Search, YouTube, Android, and Google Cloud. The structure allowed the core business and newer ventures to have clearer management and financial reporting while preserving Google’s position as the group’s central source of revenue.
Alphabet became one of the world’s largest companies by market capitalization because investors valued its dominant digital advertising business and its potential in cloud computing, artificial intelligence, and other fields. It is sometimes incorrectly called “Google” in market-cap rankings, but Alphabet is the listed parent company.
