Alphabet Inc. is an American multinational technology conglomerate holding company headquartered in Mountain View, California. Alphabet is one of the Big Five American information technology companies, alongside Amazon, Apple, Meta and Microsoft.

Google was founded on September 4, 1998, by Larry Page and Sergey Brin while they were PhD students at Stanford University in California. Together they own about 14% of its publicly listed shares and control 56% of the stockholder voting power through super-voting stock. The company went public via an initial public offering (IPO) in 2004. In 2015, Google was reorganized as a wholly owned subsidiary of Alphabet Inc.

The company has since rapidly grown to offer a multitude of products and services beyond Google Search, many of which hold dominant market positions. These products address a wide range of use cases, including email (Gmail), navigation (Maps), cloud computing (Cloud), web browsing (Chrome), video sharing (YouTube), productivity (Workspace), operating systems (Android), cloud storage (Drive), language translation (Translate), photo storage (Photo), video calling (Meet), smart home (Nest), smartphones (Pixel), wearable technology (Fitbit), gaming (Stadia), music streaming (YouTube Music), video on demand (TV), artificial intelligence (Assistant), machine learning APIs (TensorFlow), AI chips (TPU), and more. Discontinued Google products include Glass, Google+, Reader, Play Music, Nexus, Hangouts, and Inbox by Gmail.

Google is also the largest search engine, mapping and navigation application, email provider, office suite, video sharing platform, photo and cloud storage provider, mobile operating system, web browser, ML framework, and AI virtual assistant provider in the world as measured by market share.
