Own a Vizio Smart TV? It’s watching you

Own a Vizio Smart TV? It’s watching you: TV makers are constantly crowing about the tricks their smart TVs can do. But one of the most popular brands has a feature that it’s not advertising: Vizio’s Smart TVs track your viewing habits and share it with advertisers, who can then find you on your phone and other devices.

The tracking—which Vizio calls “Smart Interactivity”—is turned on by default for the more than 10 million Smart TVs that the company has sold. Customers who want to escape it have to opt-out.

In a statement, Vizio said customers’ “non-personal identifiable information may be shared with select partners … to permit these companies to make, for example, better-informed decisions regarding content production, programming and advertising.”
