Austin’s South by Southwest (SXSW) festival was founded in 1987, just a year after Rick Doblin formed the Multidisciplinary Association for Psychedelic Studies (MAPS). It started as a music festival, with 700 registrants on its first day. Today, the event—which includes a film festival, conference, and more—attracts over 300,000 people each year, according to the City of Austin.
