Clearly, TED Talks have become really popular. In fact, earlier this month, TED announced that it has surpassed a billion video views, and that likely doesn’t even take into account the talks watched on Netflix or television.

In fact, they’ve become so popular that despite being completely free to watch online, they’re being sold as bootleg DVDs in China:

Emily McManus writes on the TED Blog:

In Shanghai, China, directly across the street from a pirated DVD shop called Movie Star is another pirated DVD shop called Better Than Movie Star … and that’s where TED’s founding video director, Jason Wishnow, discovered this pirated DVD (which, sigh, but it’s too good not to share).

It’s a bootleg copy of one of our most popular Netflix shows, a curated collection called “Sex, Secrets and Love.” You can watch this collection yourself on Netflix Streaming, or find it on DailyMotion. Or, if you’d prefer a hard copy, did you know: You can order up a DVD of your favorite six TED Talks through our DVD on Demand service. And as with this bootleg above, you can make your own cover art …

Here’s TEDTalks: Sex, Secrets & Love on Netflix, if you’re interested.

What next? Bootlegs of Khan Academy videos?
