We own and operate several Mediacore based sites, which we've managed to monetize effectively with both video and display ads because we're an ad network.
We're interested in doing the same for other parties that use Mediacore to power their sites as we have clients looking for more inventory than we can provide.
If you interested in discussing a partnership where we represent your ad inventory so that you can focus on content and traffic generation (something else we can help with), please visit this page and submit a publisher application. In the comments section just mention that you found us through the Media Core Community forum.

I look forward to hearing from some other Mediacore users.
