What your smart TV knows about you – and how to stop it harvesting data

Modern TVs gather data that can be monetised. How much of this surveillance can you avoid without turning your smart TV dumb?

Watching TV feels like a benign pastime, but as all TVs become “smart” – connected to the internet via your router – they are gaining the ability to watch you too.

Then there are the devices you plug into your TV, such as Google’s Chromecast, Apple TV and Amazon’s Fire Stick.

A TV is no longer just a device for showing you content – it has become a two-way mirror allowing you to be observed in real time by a network of advertisers and data brokers, says Rowenna Fielding, director of data protection consultancy Miss IG Geek. “The purpose of this is to gather as much information as possible about your behaviour, interests, preferences and demographics so it can be monetised, mainly through targeted advertising.”

Cutting-edge tech is often super-expensive, difficult to use and less than slick. Not so for Samsung’s latest folding screen phones.

As firm’s stock falls over sales warnings, it has competition in bid to be the best smartphone
