Instagram Live is a feature on the Instagram platform that allows users to broadcast live video to their followers in real-time. This interactive tool enables viewers to join the stream, comment, and ask questions, creating a dynamic experience. Users can go live for up to four hours, making it a popular choice for events, Q&A sessions, and casual chats. When a user starts a live video, their followers receive a notification, encouraging immediate engagement. After the broadcast ends, the video can be saved to the user's Instagram profile or shared as a story, allowing others to view it later.
