Is this service special ?

Hey
I want to ask you guys something. I live in Switzerland and here we have a service called Zattoo. Its a online tv streaming service. I can use this on my iPad / iPhone /Android and any browser on any computer and stream it all to my apple tv. There are about 114 channels that you get for free ( with ads while you switch channels ) or you pay 6$ a month and there are no ads.

The great thing about it is, if i choose to pay the 6$, I can also rewatch any programm on any channel 3months back.

So i wanted to ask if this is special or is there anything like this in the USA or elsewhere?
Thats the way I watch tv.
