What is DRM (Digital Rights Management)
DRM prevents unauthorized copying and redistribution of digital content. It's why you can't download a Netflix video and share it — and why password-sharing crackdowns are technically enforceable.

The Basics
Digital Rights Management (DRM) is a set of technologies that control how digital content can be used, copied, and distributed once it's been delivered to a device. It's the reason you can't save a Netflix movie as an MP4, the reason Spotify downloads disappear when you cancel, and the reason screen recording a 4K HBO Max show often produces a black video file. Every major streaming service — Netflix, Disney+, HBO Max, Hulu, Apple TV+, Prime Video, YouTube, Spotify, Apple Music, Tidal — uses DRM to ensure that only paying subscribers can actually play the content they've licensed to show you. The concept dates back to the 1990s with software like Adobe's early eBook protection and Apple's FairPlay for the iTunes Store, but the version that matters for modern streaming is the system that pairs encrypted video delivery with hardware-level decryption on your specific device.
