Sense: noun/1
Streaming, broadcasting, webcasting, and downloading are all ways to deliver audio or video content, but they differ in method and scope. Broadcasting traditionally uses radio waves or TV signals to send content to a wide audience at a scheduled time — think of a live news programme on television. Streaming sends the same kind of content over the internet and lets the viewer start, pause, or rewind at any time. Webcasting is a narrower term that refers specifically to streaming a live event online, such as a conference or a concert. Downloading, in contrast, saves the entire file to your device before you can play it, while streaming plays the content in real time without keeping a permanent copy. For example, 'Quinn watched the match through a live streaming service' means the video played as it arrived; 'Bao downloaded the match to watch later' means he saved the file first.
Etymology
The word 'streaming' comes from the Old English 'strēam' meaning a steady flow of water, combined with the suffix '-ing'. The educational meaning, referring to grouping students by ability, emerged in British schools during the 1960s. The internet-media meaning appeared in the 1990s as technology allowed audio and video to be delivered over the web as a continuous 'stream' of data, and became widespread in the 2000s with the rise of platforms like YouTube and Netflix.
