The Internet TV service is becoming more common, and there are many websites that offer free or through a subscription rather economically. An example of these portals is Joost, who recently decided to migrate all Web flash (like YouTube) and put aside his client desktop (which only ran under Windows, and it was bastaaaante pesadito I must admit). We also have over there at the service known as Hulu, Veoh, Dailymotion or YouTube.
There are also some programs such as Winamp, the wmplayer, the MPlayer or Totem, which allow us to see streamings TV online and some (like the case of Winamp) include a manager of this content online.
A while ago I found out there surfing the Internet portal LiveStation, who offer this service along with software that is really very comfortable. What I liked is that this program is available for Windows XP and Vista (does not require Silverlight), for Mac (Tiger and Leopard) and Linux (say it is experimental, but the truth I go to Wonderland). < >
There are several stations supported by them, and some that are hundreds more out there running around, and while they do not take care of the quality of these channels, which I have seen going very well. And unlike Joost, the people of Livestation still betting on the desktop clients.
The truth, I loved the service, much like the presentation quality. Here are some screenshots of the customer left:
