One of the big things right now is the DJ is a spectacle, isn't it? You have the enormous light show, smoke, explosions, and fire. There's a dude with a USB stick playing somewhere in there, but the spectacle is created out of lights and lasers and whatever. The original idea of DJing - being a shadowy figure in the corner while people were having a party - is not the one that makes money and is massively popular internationally.
