The Longtail

google paid $1.6 billion for Youtube in 2006 because they were interesting in it as there are lots of ads and the amount of traffic (popularity) using Youtube then loads of people would see the ads and make money from it.
top 30 most viewed videos - 29 of them are music videos with gingham style being number one and the other one is a user created video called 'charlie bit my finger' that is number 5. this shows that a lot of Youtube is dominated by msuci videos. although this could be argued because a lot of people don't watch the music videos they just listen to it as background music when doing something else.
