DRM

Petrified of piracy, Hollywood has long relied on technical means to keep copies of its output from making the rounds on peer-to-peer networks. It hasn't worked: Tools to bypass DRM on just about any kind of media are readily available, and feature films often hit BitTorrent even before they appear in theaters. Unfortunately for law-abiding citizens, DRM is less a deterrent to piracy than a nuisance that gets in the way of enjoying legally obtained content on more than one device.

             It's not what it is, it's what it isn't--axing DRM means no more schemes to prevent you from moving audio or video from one form of media to another. The most ardent DRM critics dream of a day when you'll be able to take a DVD, pop it in a computer, and end up with a compressed video file that will play on any device in your arsenal. Better yet, you won't need that DVD at all: You'll be able to pay a few bucks for an unprotected, downloadable version of the movie that you can redownload any time you wish.
             Technologically speaking, nothing is stopping companies from scrapping DRM tomorrow. But legally and politically, resistance persists. Music has largely made the transition already--Amazon and iTunes both sell DRM-free MP3s that you can play on as many devices as you want.
Video is taking baby steps in the same direction, albeit slowly so far. One recent example: RealNetworks' RealDVD software (which is now embroiled in litigation) lets you rip DVDs to your computer with one click, but they're still protected by a DRM system. Meanwhile, studios are experimenting with bundling legally rippable digital copies of their films with packaged DVDs, while online services are tiptoeing into letting downloaders burn a copy of a digital movie to disc.
That's progress, but ending all DRM as we know it is still years off. Keep your fingers crossed--for 2020.
