Failure from the get go!
Youtube is used by people that don't want to pay for content anyways most of the content is made by 12-30 something year olds and I doubt any of them want to pay for youtube content.
Also most people are now flocking to the ad free videos and ditching channels like vevo for music lyric videos to get rid of the horrible ads vevo puts out.

Given there is tons of good content on youtube that you can't get via pay channels, I'd say it is far from failure. Hell, we have a full cable subscription here but these days I find more of my TV hours are spent on Youtube than your average cable channel.
I'm pretty sure if it was a 'failure', Google would have done something a long time ago or not acquired it to begin with.
I swear, some people should have pace-makers installed to free up the resources. Breathing and heart beat taxes their whole system, all of their brain cells wasted on life support.-two bit brains, and the second bit is wasted on parity! ~head_spaz
