The Assembly demo party is a demoscene and gaming event in Finland. The most recent Assembly was held from the 4th to 7th August 2011 at Hartwall Areena in Helsinki.
The first Assembly was held from July 24th to July 26th 1992, in Kauniainen. It was organized by the Amiga demo groups Complex and Rebels, and the PC demo group Future Crew. The staff grew into a large non-profit group of individuals known as Assembly Organizing. Through the 1990s, Assembly grew so large that even exposition halls no longer sufficed, and only the largest of sports arenas met the partygoers’ needs. In 1999 they rented the largest sports arena in the country, Hartwall Areena in Helsinki, with over 5000 visitors and 3500 computers on the ice rink and it has been held there ever since. As of 2011 the party has been held for 20 consecutive years.
