I'd rather expect a HDMI cables that will display ads if you don't pay a subscription will come first. Pretty sure we had a thread on this not so long ago.
I’m waiting on Panasonic (Panasonic, was it?) to act on their trademark to have interactive ads on their TVs. You have to yell a product name or marketing keyword (McDonalds! PlayStation!) out loud if you want the ad to stop. It stays if you can’t or don’t yell :)
