Pecha Kucha, the Japanese term for the sound of conversation (“chit chat”) began in Tokyo, back in 2003. Conceived by Astrid Klein and Mark Dytham, their original goal was to create a space where designers could share their ideas/passions with others.
In order to prevent speakers from droning on and on, the Pecha Kucha format has restrictions: namely, 20 slides, on display for 20 seconds each. The images advance automatically and you talk along to the images. Because of this constraint every single Pecha Kucha presentation, regardless of speaker or topic, is exactly 6 minutes and 40 seconds in length.
