All your life, you've had shows you loved canceled because some mystery idiot with a Nielsen box refused to watch.
Now... YOU have the power.
Swing by this place (near the MGM Grand pool entrance) and you'll sit down to see a mystery show. As you watch, you turn a nob on a Nielsen controller. You're just letting them know how much you like a given moment in a show. And if you hate it, you can drop the knob to zero... and even hit the "tune out" button.
Afterward, you fill out survey questions about the show.
It's surprisingly fun.
When my girlfriend and I did it, we both HATED the host of the reality show we watched. As soon as we got out, I asked her what she thought and she started ripping the host apart. I had never been more attracted to her.
For your time, they give you an envelope of coupons, but I didn't get the $20 bill some other Yelpers got. Even without the incentives, it's cool to have something free to do after you lose all your money in the casinos. And who knows... you might get to see the next great hit or the next spectacular flop before the rest of the country!
Note: They can't tell you what show you'll watch, but they will tell you what it's rated.
