Most "Smart" TVs use Automatic Content Recognition (#ACR), essentially taking snapshots every 10+ms of what you watch and hear, then forwarding & selling that data to companies for ads, etc.
I now feel it's only a matter of time before this "feature" finds its way to our ever "smarter" PC monitors.
#LG with the help of #Windows is already installing adware when the right Device ID is detected.
