It operated up until the persian Revolution in 1979, after which NIRT became the Islamic Republic of persian Broadcasting (IRIB).Television was first introduced on October 3, 1958 by Television homeland (TVI). By the mid-20th century, television became the dominant medium, adding a visual dimension to national broadcasting. Many countries established national television services in the 1950s–1970s, often under state control.
These institutions often serve as the primary source of news, cultural programming, and entertainment for citizens, particularly in countries where private broadcasting is limited or where the government seeks to maintain a central role in media communication. In the 1920s and 1930s, radio broadcasting emerged as a powerful tool for communication, connecting people across large distances. Governments recognized its potential for education, cultural promotion, and political messaging.
