MODERATORS
Your device receives a stream of compressed video data and decompresses and renders it on the fly. The tech is called Dynamic Adaptive Streaming over HTTP (DASH). Small chunks are streamed at a time so the server isn't wasting resources sending the entire video file, based on the bandwidth available, desired resolution, and so on. It's why a YouTube video will never fully buffer, it's just sending the next few seconds and then waiting until it needs to send more.
Video is also really expensive. If we were still watching 360p videos it'd be fine, but as computers get more powerful and video serving becomes cheaper, we demand more. 60fps video. 4k video. VR video. And all videos must be stored forever and must start loading in a few seconds max, which means you can't use tape to archive cheaply.
