History
In the early 1980s, "intelligent" television receivers were introduced in Japan. The addition of an
LSI chip with memory and a character generator to a television receiver enabled Japanese viewers to receive a mix of programming and information transmitted over spare lines of the broadcast television signal. A patent was filed in 1994 (and extended the following year) for an "intelligent" television system, linked with data processing systems, by means of a digital or analog network. Apart from being linked to data networks, one key point is its ability to automatically download necessary software routines, according to a user's demand, and process their needs.
However, descriptions of the elements of a smart television can be found in public discourse from the beginning of the 1980s, if not earlier, with the introduction of

The mass acceptance of digital television in the mid-late 2000s and early 2010s greatly improved Smart TVs. Major TV manufacturers have announced production of Smart TVs only for their middle-end to high-end TVs in 2015. Smart TVs became the dominant form of television during the late 2010s. At the beginning of 2016,
Nielsen reported that 29 percent of those with incomes over $75,000 a year had a Smart TV.
