Whatever Happened To Video Chatrooms?

Maybe back 10 years ago, there were some awesome sites where you would go into a chatroom with random people and start casting yourselves through cam. There were tons of different chatroom options like, "bud smokers only" "emo" etc etc.  What happened to those sites?  

Did they all just morph into sites where everyone just tunes into 1 person like twitch and mfc?
