Apple iTunes Music Store

Year released: 2003 

Just Blaze: "Along with the iPod, I would have to name the iTunes Music Store. For the first time you could easily go online and buy music legally. At the time it was encoded with DRM, but just the fact that you could buy all this music was big. And I think it played a strong point in proving to the industry: Don't be afraid of the digital revolution. Just play nice with it. The first day the iTunes Music Store launched I spent $700."
