TED & TEDx
TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages. Meanwhile, independently run TEDx events help share ideas in communities around the world.
TED取的是 “Technology技术”, “Entertainment娱乐”, “Design设计”三个单词的首字母，这是美国的一家私有非营利机构，以TED大会著称。TED专门邀请站在各个领域前沿的创新者和实践家来做18分钟以内的演讲，旨在传播有独特的思想来改变生活态度，进而改变世界。
TEDx are independent TED-like events, which can be organized by anyone who obtains a free license from TED, agreeing to follow certain principles.
TEDxXi’an was officially founded in 2015, hoping to discover more worthy ideas and stories, thereby inspiring this city and letting the unique voices be heard by the world.
