Alphabet replaced Google as the publicly traded corporate name in 2015.
Google reorganized under a new holding company called Alphabet Inc. in October 2015. Alphabet became the parent company, while Google remained the main subsidiary responsible for search, advertising, Android, YouTube, and related products.
The restructuring separated Google’s core internet businesses from other projects, including health technology, self-driving vehicles, and investment activities. Larry Page became Alphabet’s chief executive, while Sundar Pichai became Google’s CEO. Pichai later became Alphabet’s CEO in 2019.
Alphabet’s market capitalization is therefore attached to the parent company rather than to a separately listed Google stock. Many people still say “Google” when discussing the group’s market value, but the exchange-listed entity is Alphabet. Its stock trades under the tickers GOOGL and GOOG, which have different voting rights.
