Consumer Watchdog, a privacy advocacy group, is running a 15-second spot on a 540-square foot digital display in Times Square to promote a longer video the group made highlighting what it perceives to be Google’s intrusions on privacy. Both the 15-second spot and the longer video feature a ghoulish caricature of Eric Schmidt driving an ice cream truck, offering “free ice cream” to children. All the while, he is taking their personal information, conducting full body scans — and in the final, longer version of the video, scaring them with secrets he has gathered about their parents.
