So there you are, walking down the street, when you hear a voice in your head. And instead of the regular voice, the one that tells you that you want a cheeseburger or that you should buy more video games, this one is an unfamiliar one telling you to watch a new TV show. Are you going crazy? Perhaps, but that's not the cause of this. Nope, it's just a new form of advertising. Awesome!
Yes, there's a new add in Soho in Manhattan that uses a speaker beaming down an "audio spotlight" that only you can hear, making it sound like it's coming from inside your own head. Is nothing sacred? If advertisers can start beaming sound into our heads from afar, what's next? In-dream advertising? I weep for the future.
