At least in USA. It's the similar thing with a lot of online business:music, videos , movies or ride sharing. First it's illegal and then someone big enough does it and it's a great business. Spotify, YouTube, Netflix, Uber etc... Technologically certainly fairly interesting but the real roadblock was regulations and contracts and conflicts of interest.
