The Sri Lanka Broadcasting Corporation (formerly Radio Ceylon) is the oldest-running radio station in Asia, established in 1923 by Edward Harper just three years after broadcasting began in Europe. The station broadcasts services in Sinhala, Tamil, English and Hindi. Since the 1980s, many private radio stations have also been introduced. Broadcast television was introduced in 1979 when the Independent Television Network was launched. Initially, all television stations were state-controlled, but private television networks began broadcasting in 1992.
