That's all well and good that Turner Broadcasting is in contact with enforcement about the locations of the billboards BUT devices aren't billboards. Hellllooo, anyone home at Turner? Oh wait, what in the world am I thinking!
See, I don't know if they were really "Devices"...
It now seems that the whole "circuit board" business may have been simply the actual appearance of the mooninite (which is basically like one of the alien enemies in the ancient "Space Invaders" video game.)
CNN lied, why should Turner be any different?
If these were paid advertising, then there should be a paper trail. Would the subway accept such advertising? Sounds like the devices were left anonymously.
