What Happened to Winamp?

Winamp used to be this nice little mp3 player.

This weekend I got tired of Winamp bugging me to upgrade, so I did. For the first time in a long time, I started exploring the new features in Winamp. That's when I discovered ShoutcastTV. I've been a Shoutcast Radio listener for a long time now. Two of my favorite shoutcast stations(?) are DI.fm and Soma.fm. But this TV thing - it's crazy. There exists a huge variety of stations playing all kinds of cotent from nutty home baked comedy to mainstream media. I watched protest videos and commercial free South Park all weekend.

How does this model work? How does someone provide media that has to be licensed on a free online stream with no commercials and make money? Subscription model? Donations?

I don't know how it works, but I love it. Thank you, Winamp... !
