In 1930, 160 km east of Dallas, oil was discovered and the city quickly became the center of the Texas and Oklahoma oil industries. In 1958, in Dallas, Jack Kilby, a Texas Instruments employee, invented the chip. When the oil industry largely shifted to Houston by the 1980s, Dallas was shifting to a booming technology boom (caused by the growth of the information and telecommunications industries), while remaining the center of the banking system and business. In the 1990s, Dallas became known as Texas Silicon Valley, or Silicon Prairie.
