Readers who buy digital media, work in tech or publishing, or care about copyright and free expression.
See why every lock on culture ends up punishing the people who paid for it.
You buy music, movies, and books, then get told how, where, and how many times you're allowed to use them. This book shows why those locks always break, why the breaking always lands hardest on honest buyers, and why messy, open systems outlast them — as when Sony's copy-proof CDs infected half a million networks with malware.
You'll understand exactly why locking down information fails, who it really hurts, and what a system built to last looks like instead.
Content — Selected Essays on Technology, Creativity, Copyright and the Future of the Future · by Cory Doctorow · Doctorow writes from direct experience — including getting locked out of his own paid-for iTunes library after his third authorized computer was flagged.
Other ways to buy
Why this matters now
You've paid for a movie, a song, or a book, and then been told what you're allowed to do with it — which device, how many times, which country. You've hit a limit you didn't agree to on something you already own.
The DVD region codes and iTunes device limits in this book are old news. The pattern isn't: the same locks now show up in ebooks, streaming subscriptions, and takedown notices you run into this year.
Who this is for
- You've bought a movie or album and then been told you're not allowed to actually use it the way you want.
- You've hit an arbitrary limit — three computers, one region, one device — on something you already paid for.
- You work in tech, publishing, or media and want to know why every DRM scheme breaks the same way.
- You've watched a takedown notice hit an independent artist instead of a pirate.
- You want the copyright and DRM arguments explained in plain terms, not legal jargon.
What you’ll get from it
- You'll learn the exact cryptographic reason DRM can't ever work — the attacker is always the customer holding the key.
- You'll see why anticircumvention law lets companies invent restrictions on you that copyright itself never granted.
- You'll understand why new formats win by doing something old media can't, not by copying old media's strengths.
- You'll recognize the same pattern running from piano rolls to VCRs to Napster to today's streaming locks.
- You'll see why takedown systems and subjective approval processes hurt working artists more than they stop piracy.
- You'll know what a decentralized, hard-to-break alternative to locked-down culture actually looks like.
Ideas at the core of the book
DRM can't keep a secret: the device that plays your file has to contain the key, so anyone who owns the device can find it.
The law that props up DRM does more than protect copyright — it lets companies write private rules no copyright statute ever gave them.
Copyright has always changed when technology changed; freezing it in place is what causes the damage, not the disruption itself.
Information behaves like a relationship and a shared process, not an object — which is why treating it as property backfires.
Locking down a format doesn't stop copying. It just decides who gets hurt first, and it's usually the honest customer.
From the book
“In DRM, the attacker is *also the recipient*. Alice sells Bob a DVD player with a CSS un-scrambler. Alice has to provide Bob—the attacker—with the key, the cipher and the ciphertext. Hilarity ensues.”
“DRM vendors tell us their technology is meant to be proof against average users, not organized criminal gangs. At the end of the day, the user DRM is meant to defend against is the most unsophisticated and least capable among us.”
“Anticircumvention lets rightsholders invent new and exciting copyrights for themselves—to write private laws without accountability or deliberation—that expropriate your interest in your physical property.”

Questions
Is this a legal textbook?
No. It's a collection of essays built on real cases — a mother trying to copy a Toy Story DVD, Sony's rootkit CDs, a teenager prosecuted for breaking DVD encryption — not abstract legal theory.
Do I need a legal or technical background to follow it?
No. The arguments run through ordinary situations: copying a disc for your kids, hitting a device limit on music you bought, a takedown notice landing on the wrong video.
Does this only apply to old formats like DVDs and CDs?
No. The same locks and legal tools now show up in ebooks, streaming services, and content takedown systems. The book traces one pattern across all of them.
Is the book against copyright?
No. It argues copyright is a practical tool that should keep adapting to new technology, not a fixed law that gets propped up with restrictions no statute ever created.
