PechaKucha Night started as a simple idea for a one-off event, devised by Astrid Klein and Mark Dytham of Klein Dytham architecture. The first event was held at their Tokyo-based creative kitchen, SuperDeluxe, in February 2003. Since then it has grown into an international movement.
There was no business plan, no notion that the format would be so successful, so global. PechaKucha ran in Tokyo monthly for three years in SuperDeluxe before people started asking if they could run it in their own cities after visiting the event in Tokyo. No city had been asked to run a PechaKucha Night -- cities always asked Astrid and Mark. A simple application process was devised with each city being granted handshake agreements to run PechaKucha Night, mainly to stop people from stepping on one another's toes in cities around the world.
When the number of cities reached double figures, Klein Dytham architecture set up a simple website. It was based on a road sign format, but when the sign reached 70 cities the site was upgraded. The site has been upgrade twice since then to cope with the number of cities and events which now run at the rate of over 60 a month.
