One thing is for certain: this story is gaining more exposure for Revolva than performing for free on the show ever would have.
It has several thousand upvotes on Reddit, has been linked and talked about on the national stage, and of course there's the spread of social media. I myself tweeted the story, posted it on Google+, and linked to it on Oprah's own fan page on Facebook. Would she have gotten any of that "exposure" by performing for free on Oprah's side stage? Nope.
Exposure has value, no doubt. I don't dismiss its worth completely. There are countless people who have come from nowhere and risen to fame because of it. Terry Fator, winner of season two of America's Got Talent is a prime example. A struggling performer for decades, the guy was pretty much the poster child for the starving artist. Now he's headlining his own show in Vegas. And there are many like him...Justin Bieber was some nobody kid who sang on YouTube before he became famous. Kim Kardashian made a porno, and now her Photoshopped body is breaking the internet.
But these famous people, while insanely wealthy and popular (like it or not), are the overwhelming minority. Yet they are what starving artist types yearn for, and what people like the producers of Oprah's show prey on. Hopes and dreams. Today you're a nobody, but just 5 minutes on our show/a blurb in our book/a photo in our magazine will make you an instant sensation. I've had my photography
featured in a
movie, and been paid for it. Not much, but paid. I've also been approached for publication, with the promise of book copies and "exposure", and turned them down.
We have to assume that none of the performers at this touring show have been paid. I doubt the producers would single out this woman and not offer to pay only her. So yes, performers are lining up for the promised exposure. There are several comments on her page (and on Reddit) from other performers/artists who feel the same way, and support her calling out Oprah on it.
