Your Smart TV Knows What You're Watching

An anonymous reader shares a report: If you bought a new smart TV during any of the holiday sales, there's likely to be an uninvited guest watching along with you. The most popular smart TVs sold today use automatic content recognition (ACR), a kind of ad surveillance technology that collects data on everything you view and sends it to a proprietary database to identify what you're watching and serve you highly targeted ads. The software is largely hidden from view, and it's complicated to opt out. Many consumers aren't aware of ACR, let alone that it's active on their shiny new TVs. If that's you, and you'd like to turn it off, we're going to show you how. First, a quick primer on the tech: ACR identifies what's displayed on your television, including content served through a cable TV box, streaming service, or game console, by continuously grabbing screenshots and comparing them to a massive database of media and advertisements. Think of it as a Shazam-like service constantly running in the background while your TV is on. These TVs can capture and identify 7,200 images per hour, or approximately two every second. The data is then used for content recommendations and ad targeting, which is a huge business; advertisers spent an estimated $18.6 billion on smart TV ads in 2022, according to market research firm eMarketer. For anyone who'd rather not have ACR looking over their shoulder while they watch, we've put together a guide to turning it off on three of the most popular smart TV software platforms in use last year. Depending on the platform, turning off ACR took us between 10 and 37 clicks.
