Alphabet is the parent company of Google and operates the DeepMind artificial-intelligence laboratory.
Alphabet Inc. is the holding company created in 2015 during a corporate restructuring of Google. Google became its largest subsidiary, while other businesses and projects were placed under the broader Alphabet structure.
DeepMind, founded in London in 2010, became part of Google in 2014 and now operates within Alphabet. Its research has included systems such as AlphaGo and AlphaFold, which demonstrated important advances in game-playing and protein-structure prediction.
Alphabet’s major business remains Google, including Search, YouTube, Android, and cloud services. This structure is different from a simple brand name: Google is a subsidiary, while Alphabet is the publicly traded parent whose market capitalization is measured in stock-market rankings.
