Google's parent company was created in 2015 under the name Alphabet Inc.
The restructuring separated Google's core internet businesses from a group of other ventures. Google remained the largest subsidiary, covering products such as Search, YouTube, Android, and Google Cloud. Other operations, including research and experimental projects, were placed within the broader Alphabet structure.
Larry Page became Alphabet's chief executive at the reorganization, while Sergey Brin became its president. Sundar Pichai became Google's chief executive and later took over as Alphabet's CEO in 2019. The structure was intended to give individual businesses greater independence while allowing investors to evaluate the overall group.
Alphabet is frequently listed among the world's most valuable public companies by market capitalization. That ranking is based on the market value of its publicly traded shares and can change daily. Alphabet should not be confused with Google's original corporate name, Google Inc., which was replaced as the top-level public company in the 2015 reorganization.
