So many dead horses
American TV networks are due for a sudden epic failure. Cable TV fees continue rocketing upwards long after people have reached the point where they no longer want to pay for it. To have TV networks sue Aereo for improving penetration into the targeted advertising market must feel like a big F-U to their other source of income. A point of no return will be reached where broadcasters are so despised that no tweaking to the price model is going to fix it.
It's a shame that this must happen now because IPTV isn't at all ready to take over. There are no widely adopted systems ready for distributing massive amounts of subscription video and there are few ISPs that aren't owned by broadcast network. Cable TV/Internet/Broadcast companies will laugh at the collapse and start selling expensive video data passes to "protect" their networks. People won't pay that either so it will just become a long, ugly standoff.
