YouTube LLC is a global online video-sharing and social media platform owned by Google LLC, a subsidiary of Alphabet Inc. Launched on February 14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim, it was acquired by Google in November 2006. Headquartered in San Bruno, California, the platform enables users to upload, view, rate, share, add to playlists, and comment on videos, as well as subscribe to other users. It hosts a vast array of content, including user-generated videos, music videos, educational content, live streams, and corporate media, making it a dominant force in online video consumption and content creation globally. The platform enforces policies on misinformation, hate speech, and other violations and has been criticized by some, particularly conservatives, for alleged bias in content moderation and demonetization policies.
