While the internet has changed the world in more ways than one could easily list, that doesn’t mean that all of those changes have been good for everyone.
One of the areas where digital technology and the internet haven’t paired well has been with intellectual property.
There has always been a thriving black market, or secondary market, for products that have been made without the consent of the copyright or trademark holder’s permission. However before the internet they rarely had any significant impact on businesses based simply on reach and scale. But with the relative anonymity and global access of the internet, the unauthorized use, reproduction or distribution of media like music, television, movies and artwork has made it easy to illegally trade and sell.
