A smart TV, sometimes referred to as
connected TV or hybrid TV, (not to be confused with IPTV, Internet TV, or with Web TV) is a television set or
set-top box with integrated Internet and Web 2.0 features, and is an example of technological convergence between computers and television sets and set-top boxes. Besides the traditional functions of television sets and set-top boxes provided through traditional broadcasting media, these devices can also provide online interactive media, Internet TV, over-the-top content, as well as on-demand streaming media, and home networking access.[1][2][3][4]
The software that runs smart TVs can be preloaded into the device, or updated or installed on demand via an app store or app marketplace, in a similar manner to how the Internet, Web widgets, and software applications (in this context commonly just referred to as "apps") are integrated in modern smartphones.[5][6][7][8][9]
