I’ll try to run through what’s currently available and where to find it.
First of all, I went spent almost 6 years studying abroad, so I know what it’s like to be on a desperate search for internet tv. For the majority of that time, it just didn’t exist. It was either a problem of not enough content or a massive fee. A lot has changed since then.
There are basically 3 or 4 very good options in 2007, but that is very dependent upon what you mean by “free tv on the internet.”
The first, and by far the most popular version of internet tv is on-demand viewing. There are several different companies that offer you the ability to watch previously-aired programs and television series for free. If you are looking, perhaps, to discover a television series that you never really got into and now you feel out of the loop, this is the way to go. If you scroll down the page later you can read some of the reviews I did on the specific sites and software.
However, this isn’t really internet “tv” to me. This is kind of like a free movie rental of a television series. That’s not what I was searching for myself, so I’ll assume there are some of you out there like me who want a real television experience on your computer (and one that isn’t going to cost you monthly fees).
