So, did you know your TV can track other devices attached to your network? I knew it was theoretically possible, but I didn't realize that's what's actually happening. Sending ads to those devices based on what you're watching?
Likewise, did you know your TV is selling the fact that are likely a Democrat or Republican based on if you watch MSNBC or Fox news more?
