Well, with you being in the states, I imagine that you pick up huge amounts of channels from canada and south america?
In europe, as soon as you invest in a satelite dish, or a cable system with a satelite head, you're exposed to channels in a huge variety of languages and covering a huge variety of tastes.
Go to the middle east and you'll find a lot of channels targetted at your nation whose signal originates in a very far off land (read Iran and L.A. for example
). If you state had total control over "Public" bandwidth, then i'm sure you can see where my line goes here...
No matter what governments try to do, they are always going to be behind the technology. They've no hope of regulating bandwidth, etc. The only way they, governments and societies, have a hope of regulating the content is through the advertisers and companies that are the fuel the media fire burns on.
Any other approach is doomed to failure.
