Saigon News Radio Live for Vietnamese people over the world. Live radio is radio broadcast without delay. Before the days of television, audiences listened to live dramas, comedies, quiz shows and concerts on the radio much the same way that they now do on television. Most talk radio is live radio where people can speak (anonymously) about their opinions and lives. Live radio is sound transmitted by radio waves, as the sound happens. Modern live radio is probably most used to broadcast sports, but it is also used to transmit local news and traffic updates. Most radio that people listen to today is pre-recorded music, and the days of solely live broadcast music are generally not as present. The radio era, known as “the shortest golden age in history”, lasted from 1930 to 1955.
