In reply to Removed User:
I know what you mean, but it is jut like i explained. I came across them by seeing the 31m video shared on facebook, then once in heir youtube page i tend to sort the videos by 'popular', so i watched the second most popular, then the third, etc. Where people stop will be scattered, and the views disparity increase.
The thing with the ads can be that once you monetise it maybe youtube starts pushing the videos more in the 'suggested' tabs?
