A “smart TV” is any television set with an internet connection and access to on-demand streaming media. Samsung uses the term as a brand name for its line of such products (Samsung Smart TV), but many other manufacturers also produce smart TVs.
Smart TVs are internet-connected televisions. Although there are many smart TV brands, models, and operating systems, almost all smart TVs have apps that let you watch TV shows and movies from streaming services like Netflix, Hulu, and HBO, all of which can be viewed securely with a VPN.
