Study Claims Vizio Simply Ignores 'Smart' TV Spying Opt Out Requests

An anonymous reader quotes a report from Techdirt: Recently, reports emerged that LG TVs are sniffing around your local network, and even listening to your local environment, even when the TV is purportedly "off." Some of those voice commands were then stored in plain text and uploaded to the internet. LG's response? To deny everything. [...] That latter point is central to a new study out of Northeastern that conducted 5,943 experiments across twelve commercial "smart" TV devices. The researchers found that most smart TVs utilize automatic content recognition (ACR), a technology that captures audio or video snapshots of viewed content and then monetizes that data to help build personalized profiles of viewers.
