The NFL has reportedly narrowed down a short list of possible performers for the 2015 Super Bowl Half Time Show (Rumor has it that Katy Perry, Rihanna, and Coldplay are all being pursued). The Super Bowl has never paid halftime performers, but they do cover the artist's travel expenses and production costs.
The issue this year is, for the first time, the NFL is reportedly asking the Halftime Show performers to pay the NFL for the privilege of performing! If the artists decline, they're being asked instead for a percentage of revenue from touring and album sales in the months following the Super Bowl.
Am I naive for thinking this is ridiculous? The Halftime Show has always been mutually beneficial for both the NFL and the performer, which is why it makes sense for no one to get paid. The NFL gains viewership and therefore collects advertising dollars, and the artist gets exposure on a national stage, which generally leads to an increase in music sales and concert tickets.
