Question about hosting a free TV show site?

So I have my service sitting around doing nothing that’s ok up to a high speed internet connection and I noticed at on sites like letmewatchthis there are a lot of free TV web sites that have ads and I know that’s probably how they make their revenue So I was wondering if any of you have any idea what sort of money does sex bring in I and if it would be possible to host of those web sites myself I pay for a domain name on possibly have that running to make some money on the side.

So if you guys have any information on that sort of thing what they make or if you have any ideas or suggestions on let me know thanks.

PS I was surprised to find that the dictation feature on iOS 6.1 .2 is actually very accurate I actually made this whole question using it.
