Great article from Scientific American. Excerpt:
"And if you don’t make your product available legally, guess what? The people will get it illegally. Traffic to illegal download sites has more than sextupled since 2009, and file downloading is expected to grow about 23 percent annually until 2015. Why? Of the 10 most pirated movies of 2011, guess how many of them are available to rent online, as I write this in midsummer 2012? Zero. That’s right: Hollywood is actually encouraging the very practice they claim to be fighting (with new laws, for example)."
