The golden age of broadcasting from the radio heyday of the 20s, 30s and 40s, when Jack Benny, Bob Hope, The Shadow, Fanny Brice and H.V. Kaltenborn ruled the airwaves, through the television era when variety, drama, comedy, sports and world history flashed into our living rooms, each day. The rise of technology and the extraordinary popularity of radio and television, in the past century, led to revolutionary changes in entertainment, news gathering and delivery, lifestyles and history represented by the sights, sounds and ephemera from a magical and legendary era. Writer Robert Campbell called this broadcasting phenomenon "the reality that changed our world forever."
