- Graphics Interchange Format (GIF)
devised by the UNISYS Corp. and Compuserve, initially for transmitting
graphical images over phone lines via modems
- Uses the Lempel-Ziv Welch algorithm (a form of Huffman Coding),
modified slightly for image scan line packets (line grouping of pixels)
- Limited to only 8-bit (256) colour images, suitable for images
with few distinctive colours (e.g., graphics drawing)
- Supports interlacing
