SXSW (South by Southwest)
South by Southwest (abbreviated as SXSW and colloquially referred to as South By) is an annual conglomerate of film, interactive media, and music festivals and conferences that take place in mid-March in Austin, Texas, United States. It began in 1987, and has continued to grow in both scope and size every year. In 2017, the conference lasted for 10 days with SXSW interactive lasting for five days, music for seven days and film running concurrently for nine days. Comedy and gaming components to the festival are particularly fast-growing (source:Wikipedia).
