More details have come in about the rumored user generated ad campaign that XM may be running next week. According to a source, XM's user generated ad campaign will be run on Current TV, and they'll be announcing it sometime "next week."

XM will supposedly be providing design elements that you can use in your ad, and viewers will be able to comment and vote on their favorite ads. So even if you're not into making the ad, at least you can participate in it.

Looking at the Current TV page, it looks like there's other campaigns currently running (like Toyota), and there's a prize of $1,000 per spot. The Current TV video also teases the potential of a $5,000 to $50,000 payout. Not sure about the prizes offered with XM's promotion, but even a grand would be nice.

More deets on this will be posted as they come in.
