Has Street Art "Jumped the Shark"?

I have been an advocate for street art for many, many years partly because I saw it as an anti-establishment form of expression, forgoing galleries and museums and bringing some pretty amazing talent directly to the people without any effete curation.

So what am I to think when I see the Metropolitan Museum of Art in NYC offering Sprayground - a Pop Up store at the museum that offers what appears to be fashion and accessories with spray paint street art graffiti designs "while supplies last"?

Well, what I think is that street art has now been co-opted by the very institutions that tried to suppress it and has effectively "jumped the shark" meaning that it is over as a revolutionary form of expression.

I don't mind museums showcasing street art - the Miami based Museum of Graffiti is a great example of how we can celebrate that art form without diminishing it. But the Metropolitan Museum of Art? Really??
