The twentieth century brought about important advances in mass media with the development and improvements of both the radio and the television. Although both are significant in the history of mass communications in the United States, the television dramatically influenced how Americans viewed the world, especially war and political activities, after mid-century. Innovations in televised programming changed daily family life, encouraging gatherings around television sets. World crises were no long thousands of miles away. For many, the Vietnam War felt like it was being fought in their living room. As televisions increased in popularity and became commonplace, the experience of world events changed greatly. From the simulcast of combat to man landing on the moon, televised events brought life into living rooms around the country and altered public understanding of the world around us.
