YouTube is a video sharing platform that hosts user-generated and licensed video content across genres such as music, education, entertainment, news, and live streams. The site enables uploading and viewing videos, commenting and rating, subscribing to channels, and creating playlists, with search and discovery tools that organize content by keywords, trends, and recommendations. It supports playback in multiple resolutions with captions and offline options in some regions, and provides live streaming and community features for creators and viewers.
