Smart TV, which is also sometimes referred to as "Connected TV" or "Hybrid TV", (not to be confused with IPTV, Internet TV, or with Web TV), is the phrase used to describe the current trend of integration of the internet and Web 2.0 features into modern television sets and set-top boxes, as well as the technological convergence between computers and these television sets / set-top boxes. These new devices most often also have a much higher focus on online interactive media, Internet TV, over-the-top content, as well as on-demand streaming media, and less focus on traditional broadcast media like previous generations of television sets and set-top boxes always have had. Similar to how the internet, web widgets, and software applications are integrated in modern smartphones, hence also the name ("Smart TV" akin to "Smart Phone").

The technology that enables Smart TVs is not only incorporated into television sets, but also devices such as set-top boxes, Blu-ray players, game consoles, hotel television systems, and other companion devices. These devices allow viewers to search and find videos, movies, photos and other content on the web, on a local cable TV channel, on a satellite TV channel, or stored on a local hard drive.
