Radio experimentation began as early as the nineteenth century. Marconi and others tried to invent a way to transmit the human voice as they had Morseas code. N...ot until the discovery of the vacuum tube by DeForrest was that dream realized. Westinghouse, General Electric and others worked feverishly on perfecting it. In 1921, after the war, Westinghouse bested other companies. KDKA in Pittsburgh went aon the air.a In the next two years hundreds of stations obtained licenses and followed suit. Radioas greatest expansion was during the thirties. Demand for sets skyrocketed. Soon, virtually every household had the awooden box that talked.a More diverse programming was developed. In addition to music, now drama, comedy and commercials were introduced. Networks and government agencies also emerged. However, it was during World War II that radio had its finest hour. No other medium could compete with radioas immediacy and instant analysis of war news. Millions of Americans tuned in regularly.Detailed info »« Brief info
