YouTube

YouTube is a video-sharing and streaming platform owned by Alphabet (Google's parent company), and one of the world's most-visited websites, serving as a central hub for video content spanning entertainment, education, and news. Launched as an independent startup before being acquired by Google, it has grown into a global infrastructure for creators, advertisers, and viewers at enormous scale.

The platform is a significant force in AI and technology: machine learning-powered recommendation algorithms shape viewing decisions for billions of users, and YouTube has invested substantially in AI-driven content moderation, search, and ad targeting. Creators participate in advertising revenue through the YouTube Partner Program, and the platform also supports subscription offerings alongside its free, ad-supported tier.

YouTube is increasingly subject to regulatory scrutiny alongside other major social platforms, particularly around child safety—the United Kingdom has moved to restrict social media access for users under 16, with YouTube among the platforms affected. The company is also expanding its social feature set, including testing direct messaging in the United States, reflecting a broader push beyond its core video-hosting identity.
