A course library people paid for
Entitlement on every request, resume where they left off, and a completion record the business can rely on.
Audio/Video Streaming
Putting video on a page is easy. Delivering it so it starts in under a second on a phone on mobile data, holds up when the connection drops, and cannot be downloaded from the page source by anyone who opens dev tools is the actual work.
That means adaptive bitrate streaming with several renditions, a CDN close to the audience, signed URLs that expire, and a poster frame so the page never shows a black rectangle while it loads. Autoplay is muted or absent, because a video that starts talking at someone is a reason to close the tab.
For anything sold, playback has to know who is watching. Entitlement checks, resume position, and progress tracking are what separate a course platform from a folder of files with a paywall in front of it.

// where it fits
The situations this is usually bought for.
Video that buffers on a phone
One large file served to every device. Multiple renditions and a CDN fix the common case entirely.
Paid content circulating for free
Direct file URLs found in the page source. Signed, short-lived URLs make casual sharing stop working.
