From the Annals of the Radio Pioneers –  In 1928, Radio station WOAI in San Antonio joined the world’s first communication network, the National Broadcasting Company. WOAI (1200 am) was the first radio station in South Texas when it signed on the air in 1922. Over the next several years WOAI was issued permits by the FRC and, later, the FCC to move the transmitter site and increase its power from 500 to 1000, 2000, 5000, and finally 50,000 Watts in 1930. Over the next decade programming on WOAI changed from mostly music to news and agricultural information breaks in between soap operas.  It now runs Fox news and an unrelenting spate of right-wing talk radio interrupted occasionally by a Spurs game.
