A smart HDTV is any Internet-connected high-definition television that has built-in apps, such as Netflix and Hulu, or a complete operating system installed, such as Android TV or Apple TV. Popular manufacturers of smart TVs include Samsung, Sony, Vizio, Toshiba and LG.
Smart TVs are often Wi-Fi enabled and may have other wireless communication capabilities, such as Bluetooth connectivity or near-field communication. Some smart TVs have a small selection of pre-installed applications for popular movie- and television-streaming services and light gaming, while others have fully functional app stores like those found on mobile devices.
Alternatives to smart TVs include streaming media players such as the Roku, Nexus Player and Amazon Fire TV. These devices bring smart TV-style functionality to traditional televisions.
