It seems common sense that some genres are more popular on YouTube than others. But how much more popular? There are a few ways this could have been compiled, but the way that I chose to give a quick snapshot was to take the top 5 channels in each genre and add up their combined views. This does not take into account the number of channels in each genre. If you are thinking of a new channel to start, you would have less competition in the Travel genre, but there is probably also less interest in that genre.
Also keep in mind that genres are determined by the channel creator when they make their channel. This means that if they chose the wrong genre, or their content focus changed when they began to make videos, this does not take this into account.
You will notice, that Music is by far the largest genre with 67% of all the views. This is due to VEVO. They are not only the most popular channel, but are followed by JustinBieberVEVO and RihannaVEVO, all of which are very popular channels.
Check it out. Are you surprised by the distribution of views?
