Earthlink wants their users/fans to create some podcast ads for them. In the past they had used traditional radio spots in podcasts, but that doesn't go over so well. Hence the contest:

The EarthLink Make Advertising Better Challenge.

If you think the ads you've heard on podcasts are ungood, or if you'd just like to make an ad and have the chance at earning some prize money, you can create a jingle, spot, or testimonial and submit it at the URL above. Podshow.com will showcase our favorites as submissions come in, and we'll run the winners as EarthLink ads. The submission deadline is July 4th.
