What is YouTube?
YouTube is an online video sharing platform with integrated AI capabilities developed by Google that enables users to upload, view, and interact with videos. Its AI systems are among the largest and most sophisticated globally, driving content recommendations and moderation. The platform's AI is integral to its core functionalities, primarily serving content recommendation, content moderation and safety, search functionality, content creation and optimization, and advertising. YouTube's AI-powered recommendation engine is a cornerstone of its success, driving over 70% of what users watch by analyzing billions of signals daily, including watch history, engagement, and content metadata. For content moderation, AI classifiers detect potentially violative content at scale, with over 75% of removed videos flagged by AI before receiving ten views. AI algorithms also improve search relevance by analyzing user queries and engagement signals. Furthermore, AI provides creators with tools for brainstorming, editing, and reaching wider audiences, and targets advertisements based on user viewing history.
