FTA is virgin territory here, but has so much potential.
What it needs is a dedicated (FTA) major network that could work with advertisers to reach as many people possible, this would also work great for Las Vegas or Orlando which spends lots of $$$ on tourism ads.
I could see The Las Vegas Channel being something Big, imagine informative programming on Casinos, Clubs, Night Life, Entertainment, even How to's on betting tables and Poker for all those intimidated by gaming.
PBS gets quite a bit of subsidies form your tax dollars, and I really like PBS programming, but lets face it were watching something that is transmitted for utility purposes, now if there was a National Parks channel for FTA that would be cool , I like that kind of stuff , informative, cultural, and definitely public interest.
Hopefully somebody with lots of money and big ideas sees the potential in FTA.
