Residents of Austin are known as Austinites. They include a diverse mix of government employees, college students, musicians, high-tech workers, and blue-collar workers. The city's official slogan promotes Austin as "The Live Music Capital of the World", a reference to the city's many musicians and live music venues, as well as the long-running PBS TV concert series Austin City Limits. The city also adopted "Silicon Hills" as a nickname in the 1990s due to a rapid influx of technology and development companies. In recent years, some Austinites have adopted the unofficial slogan "Keep Austin Weird", which refers to the desire to protect small, unique, and local businesses from being overrun by large corporations. Since the late 19th century, Austin has also been known as the "City of the Violet Crown", because of the colorful glow of light across the hills just after sunset.In 1987 Austin originated and remains the site for South by Southwest (stylized as SXSW and colloquially referred to as South By), an annual conglomeration of parallel film, interactive media, and music festivals and conferences that take place in mid-March.
Emerging from a strong economic focus on government and education, since the 1990s Austin has become a center for technology and business. A number of Fortune 500 companies have headquarters or regional offices in Austin, including 3M, Amazon, Apple, Google, IBM, Intel, Oracle, 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 over 50,000 students attend.
