Emerging from a strong economic focus on government and education, since the 1990s, Austin has become a center for technology and business. The technology roots in Austin can be traced back to the 1960s when Tracor (now BAE Systems), a major defense electronics contractor, began operation in the city in 1962. IBM followed in 1967, opening a facility to produce its Selectric typewriters. Texas Instruments setup in Austin two years later, Motorola (now NXP Semiconductors) started semiconductor chip manufacturing in 1974. BAE Systems, IBM, and NXP Semiconductors still have campuses and manufacturing operations in Austin as of 2022. A number of Fortune 500 companies have headquarters or regional offices in Austin, including 3M, Advanced Micro Devices (AMD), Amazon, Apple, Facebook (Meta), Google, IBM, Intel, NXP Semiconductors, Oracle, Tesla, Texas Instruments, and Whole Foods Market. Dell's worldwide headquarters is located in the nearby suburb of Round Rock. With regard to education, Austin is the home of the University of Texas at Austin, which is one of the largest universities in the U.S., with over 50,000 students. In 2021, Austin became home to the Austin FC, the first (and currently only) major professional sports league in the city. History Austin, Travis County and Williamson County have been the site of human habitation since at least 9200 BC. The area's earliest known inhabitants lived during the late Pleistocene (Ice Age) and are linked to the Clovis culture around 9200 BC (over 11,200 years ago), based on evidence found throughout the area and documented at the much-studied Gault Site, midway between Georgetown and Fort Hood. When settlers arrived from Europe, the Tonkawa tribe inhabited the area. The Comanches and Lipan Apaches were also known to travel through the area. Spanish colonists, including the Espinosa-Olivares-Aguirre expedition, traveled through the area, though few permanent settlements were created for some time. In 1730, three Catholic missions from East Texas were combined and reestablished as one mission on the south side of the Colorado River, in what is now Zilker Park, in Austin. The mission was in this area for only about seven months, and then was moved to San Antonio de Béxar and split into three missions. During the 1830s, pioneers began to settle the area in central Austin along the Colorado River. Spanish forts were
