Hi, As probably much you know gangnam style is the most viewed video on the youtube and most successful video on iTunes. Some youtube marketer estimates that PSY (gangnam style singer) made ~ $8 million only from gangnam style on youtube. So my question is why Gangnam Style? What is so special about this video? In my idea there are really better videos on youtube or iTunes but they are not so much popular! Also how PSY made this video so so so viral?!! After 5 months hits 1 billion views! It's really not a joke! There has to be something that we don't know!
