Television was introduced in Iran in 1958. Although the 1974 Asian Games were broadcast in color, full color programming began in 1978. Since the 1979 Revolution, Iran's largest media corporation is the Islamic Republic of Iran Broadcasting (IRIB). Despite the restrictions on non-domestic television, about 65% of the residents of the capital city and about 30 to 40% of the residents outside the capital city access worldwide television channels through satellite dishes, although observers state that the figures are likely to be higher.
