Ehhh..mediocre at best right now (I would say). You see the occasional sale and usually when you do, it's a decent $XXXX price at minimum. The only problem is, I don't see as many as I'd like. Looking at the recent .TV sales on Flippa, there doesn't appear to be a big market for them there.
I like TV personally, and own some myself.. I just wish the market would start picking up on them some more too!
