Not sure where to post this (apologies if it's in the wrong place, feel free to move to somewhere more appropriate), but I'm looking for people in the web industry who represent (ad firm, design firm, in-house department) sites in the general 'entertainment' industry.

Examples include sports, liquor, journalism, any site with a young demographic that can benefit from adding user-submitted videos to their site...

We've got a technology we'd like to demonstrate, and are willing to provide service to the right company - the question is, where would one find representatives for these types of companies?
