In the close future, LEDs are expected to be gradually replaced by OLEDs. Also, major manufacturers have announced that they will increasingly develop smart TVs in the mid-2010s. intellectual TVs past integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s.
Television signals were initially distributed only as terrestrial television using high-powered radio-frequency transmitters to present the signal to individual television receivers. Alternatively television signals are distributed by coaxial cable or optical fiber, satellite systems and, previously the 2000s via the Internet. Until the into the future 2000s, these were transmitted as analog signals, but a transition to digital television is traditional to be completed worldwide by the late 2010s. A pleasing television set is composed of compound internal electronic circuits, including a tuner for receiving and decoding broadcast signals. A visual display device which lacks a tuner is correctly called a video monitor rather than a television.
