A webcast is a live, streaming audio or video broadcast that is transmitted over the internet. A webcast is similar to a television or radio broadcast, but is delivered over the internet, rather than over the airwaves. Webcasts are often used for events, such as concerts, conferences, or news broadcasts, and can be viewed by anyone with an internet connection. Webcasts can be accessed using a web browser, or a dedicated media player or app, and can be delivered using a variety of technologies, such as HTTP Live Streaming (HLS) or Dynamic Adaptive Streaming over HTTP (DASH). Webcasts can be streamed live, or can be recorded and made available for on-demand playback. Webcasts are often used for a variety of purposes, including entertainment, education, and communication.
