Hello!
In venezuela we already have a (really small) participation in Radio and TV. Past Flisol2009 give us the opportunity to be on tv (for about a minute) and also a couple of radio interviews about free software and fedora (I made one and Wilmer "K0k" Jaramillo give another).
I have the resources to this files (Spanish links) but I think is viable for us to even make a tv show (maybe a 5 minutes clip weekly) in a Caracas tv station and in a Radio who transmit in all Venezuela middle towns.
Now that I read that there is a true interest in this I will start working and see what can came out :)
