The essence of the internationally renowned Ars Electronica Festival is interdisciplinarity, promoting an open encounter between international experts from the arts and sciences and an audience with highly diverse backgrounds and a variety of interests. Since 1987, the Prix Ars Electronica has served as an interdisciplinary platform for everyone who uses the computer as a universal medium for implementing and designing their creative projects at the interface of art, technology, and society. The Prix As Electronica, the Ars Electronica Festival, the Ars Electronica Center—Museum of the Future, and the Ars Electronica Futurelab are the four divisions that comprise this annual festival, whose specific orientation and long-term continuity make it a unique stage for digital art and media culture.
