A smart TV (or connected TV) is a television set with integrated internet and interactive features, representing a convergence of computers, televisions, and digital media players that allows users to stream videos, browse the web, and use apps. Unlike traditional TVs, smart TVs run a preloaded operating system and feature an app store, enabling users to install and uninstall applications like Netflix, Hulu, Spotify, and YouTube. This technology is also found in external devices such as set-top boxes, game consoles, and Blu-ray players, and it is distinct from Internet TV or IPTV, which refer to content delivery methods rather than the device platform itself. Smart TVs can access content from local network storage via DLNA/UPnP as well as internet-based services like video-on-demand, catch-up TV, and interactive advertising. The concept originated in the early 1980s when "intelligent" television receivers were introduced in Japan, using LSI chips with memory and character generators. A defining feature is the public software development kit (SDK) or native development kit (NDK), which allows third-party developers to create apps that work across different hardware manufacturers.
