Alphabet operates Google Search and YouTube under its corporate group.
Alphabet Inc. became Google’s holding company in 2015 through a corporate restructuring. Google remained the largest business within the new group, while other activities were organized as separate operations or subsidiaries.
Google Search is Alphabet’s flagship internet-search service, and YouTube is its major online-video platform. Alphabet also includes businesses and projects connected with cloud computing, artificial intelligence, hardware, autonomous vehicles, and other technologies.
The name change can cause confusion because people still commonly say “Google” when referring to the company’s products. Alphabet is the publicly traded parent corporation; Google is the principal subsidiary and brand family. Alphabet’s advertising business remains central to its financial performance.
