Does it matter if our TV is tracking us - Analysis of 81 devices including ones from Samsung, LG and Roku - 72 of the devices sent data to a destination that was not the device manufacturer itself Moreover, data firms use TV IP addresses to link what people are watching to what they do and see on smartphones, tablets and laptops, he said. “It’s like your TV is following you around,”

The Princeton report discovered that information being sent from devices also originates with channels being viewed through the use of trackers, which are predominantly managed by Google and Facebook. Eighty-nine percent of Amazon Fire TV channels and 69 percent of Roku channels contained trackers collecting information about viewing habits and preferences, researchers found.

These trackers also feature information that can uniquely identify the device and where it’s being used, including device serial numbers and IDs; Wi-Fi network names; and Wi-Fi identifiers known as MAC addresses.
