Perhaps it could be said that X-Factor, The Voice, the TV talent shows are a new culture. Not one that I particularly approve of myself, but they are widely watched and perhaps have hoovered up a proportion of consumers who otherwise might have been screaming at The Beatles.

Reality/Celebrity endorsed music must be the biggest sub-culture for a long time. There are hordes of people out there who only ever buy music from people who have appeared on these TV shows. Their concerts sell out in minutes and they can be huge exports into other 'territories' as well.
It may not be very 'sub' but it's definitely a big cultural movement.
