A short conversation with a student recently revealed something I hadn't thought of.  Everybody enjoys streaming Netflix.  It's accessible, affordable, and the best way to enjoy high end, high-def blu-ray content without spending $30+ per disc.  Tons of great content, both classic and new (well, somewhat new).  It was just a few years ago you could only stream a limited selection of movies to a PC.  Now you can stream to a Mac, iPhone, iPad, Apple TV, select Android phones, and all major game consoles.  Blu-ray players and televisions now come with built-in Netflix apps, which I believe has really allowed the company to expand to where it is today.
