Over 40 million US households own smart TVs, a category that made up more than half of TVs shipped globally in the first quarter of 2016. These high-tech internet-connected displays offer viewers the ease of access to services like Netflix, games, and social media without a Roku, Chromecast, or other media streamer — but they also may be tracking your viewing habits and listening to your conversations.

"Smart TVs are testing the privacy expectations that consumers developed in the era of traditional television," said Bureau of Consumer Protection director Jessica Rich in her opening remarks at last fall's smart TV workshop hosted by the Federal Trade Commission.

Today's WikiLeaks release revealed that Samsung smart TV owners are particularly vulnerable to spying. Newly published documents detail a program called "Weeping Angel," an attack designed by the CIA and United Kingdom's MI5/BTSS that makes Samsung smart TVs look like they're turned off when, in fact, they're not.
