Alphabet Inc. operates Google Search and YouTube through its corporate structure.
Google is Alphabet’s largest subsidiary and includes the search engine, YouTube, Android, Chrome, and Google Cloud. Alphabet was created in 2015 so that Google’s core internet operations could be separated from newer or more experimental businesses under a single holding company.
Alphabet is often ranked among the world’s richest companies by market capitalization because digital advertising remains a major business and because investors also value cloud computing, mobile software, video, and artificial-intelligence research. YouTube is not a separately listed company. It is owned and operated within Google, which in turn is owned by Alphabet.
