Artists or commercializing?

In the age of free media: pandora and youtube, hulu, ect. I wonder how many people are still all for "art for the sake of art". While I think that commercializing is not always the way to go, what options do artists have? The whole new youtube "anyone can be a star" phenom is interesting to me, because there is an expectation of getting things for free through the internet. It is also the age of instant gratification, where if I want to buy that song or that album, I no longer need to drive all the way to the store - I can download it in seconds.

The reason why I bring this up again is because of the b-boy scene and other areas of Kpop. Is b-boying too commercialized in Korea now? Or even in the United States? What about "Americas Best Dance Crew"? And what expectation do we have for this form of street art? Do people expect it to be free because it is a "lower" art form?
Would you pay to see a b-boy performance or would it be just cool to see it for free on the streets? If the b-boyers actually want to do this as a living, to support themselves, what are their options? Major yearly competitions or other smaller dance competitions require practice, which means not having another job or having another job and then as a side-job b-boying. Is that realistic? We saw the b-boys who were not from Seoul, not from rich families, who needed to provide for their families. Can they provide just as performers?

Perhaps it isn't the right venue to try and earn money. You aren't in it for the money. True. It's art, you love it, ect. However, when does it become detrimental to be a performer? An artist? But how about not to help financially support your family, but just even to support yourself financially? One of the b-boyers in Planet B-boy mentioned that he 'works to dance, not the other way around'.

There are a couple of shows featuring b-boys in Korea, including Ballerina who loves b-boy which features "Extreme Crew". Some randomly appear on television shows, variety shows, even some in Kpop (though this is more rare). For example, I had a clip up last time of the variety show Heroes where b-boys appeared on the show to teach female celebrities how to b-boy. Is this selling out? Or is it spreading b-boy? If it is becoming more "acceptable" in mainstream culture, is that bad or good? Would you rather have b-boy stay more underground or float to mainstream so more people know about it?

You can use this for other areas of art as well. The sudden influx of people interested in musicals and certain musical actors after the show GLEE. The rise of youtube stars - would you pay for their music and their songs?
