Hi duskdawn,
As a big fan of dot tv myself, I agree with all of the opinions above! I think the websites with this extension are really cool. Most of them have video streaming, and are very informative, entertaining, on-demand (that's the best part unlike traditional tv's). Check this out :
http://www.governmentview.tv/gov_info_learnmore.html - The next generation of broadcasting! Sounds good

Same website also has these channels and they all have dot tv extension, what else could it be???
http://www.medicalview.tv/,
http://www.dmbc.tv/
Today I came across
GolfBug.TV. I think this golf website is the first golf channel online. It seems really good. Sometimes I watch
High.TV and
Sail.TV, not very often though, but I think the number of visitors of these websites are increasing rapidly - the best part is that you can watch from anywhere in the world. You don't need a cable, satellite, etc. It's freedom! As long as you have the internet connection, you are free! Here some other sports sites, of course with dot tv extension:
WorldHockey.TV,
FieldHockey.TV,
Cycling.TV. Can you imagine these web sites with other extensions? That would be nonsense. Dot TV will be the best extension in the near and far future! Even better than .com when it comes to video streaming. Many companies will broadcast infomercials of their products and/or services on their own websites. And most probably these companies will start using dot tv besides having dot com websites. I believe sport events online will attract many visitors to these dot tv websites. Here is another sport channel online:
GlobalSport.TV. It looks like a good one too. To make it short, I love dot tv and I will try to keep the ones I have as long as I can because I believe each dot tv name will be very valuable in the future - even the long ones!
P.S. I haven't read many of the threads about dot tv. If there is any post or thread giving the same websites as an example, sorry about that. They all are new to me (except sail.tv and high.tv - I just wanted to share them with you to show how suitable dot tv is for this kind of websites.......)
