Ustream.tv appears to be on the cutting edge of a new form of video blogging which may possibly be called “live blogging” in the future. I first ran into Ustream.tv shortly after Justin.tv launched, but didn’t think much of it. Then, Chris Pirillo put on a show which combined video streaming, irc chat, skype, free conferencing and twitter to create a very interesting interactive experience.

That was really cool, but what makes this even cooler is the bandwidth aspect. For most web cam services you will have to stress out about your ISP terminating your services because of your video stream sucking up bandwidth. With Ustream.tv you upload to Ustream.tv first and they take the bandwidth hit - so you could have hundreds of simultaneous viewers instead of a handful.

Anyway, take a look, sign up and play around… I have a feeling this is going to be the next big thing!

This cam comes to you live from a college radio station in Washington, DC. The station is WRGW, and if you go here you can listen live while you watch the DJ’s goofing off. Just kidding.

The Empire State Building cam comes to you live from the top of the Empire State Building in New York, New York. This cam is just like the Hard Rock Hotel Pool cam - you select an area in the view finder to move around and zoom in. Even though the viewfinder picture is old, the resulting image will be live. This cam has several preset views and photo album as well.

This web cam comes to you live from inside a Bar or Cafe in Bilbao, Spain. Watch people drinking, eating and chatting with streaming video. Enjoy!
