A sixel is six pixels in vertical orientation, transferred as a unit. It was first used to send graphics to DEC printers. The next application was to transfer soft fonts to the VT220, and later terminals expanded on this.

Around 2010 [number pulled from thin air], the sixel format was rediscovered and used with modern terminal emulators for things like video playback.
