The Mekka & Symposium was a convention, known as a demoparty, where demogroups released works of art consisting of music, graphics, animation, and text, on various different hardware architectures. It began in 1997, as the result of a merger between the previous year's Mekka and Symposium demoparties, and ran until 2002. It was succeeded by the Breakpoint demoparty, which ran from 2003 to 2010 and by the Revision demoparty, which began in 2011.
On April 23, 2000, at the fourth annual Mekka & Symposium, a group known as Hitmen premiered the world's first non-commercial independent code running on the Sega Dreamcast, the A.G.E. demo. It utilized a custom cable to connect to a host computer called the Dreamcast Debug Handler.
