What connection does the company Compuserve have with gif’s?
CompuServe introduced the file format in 1987 to provide color images for their file downloading sites, replacing their RLE format that handled only black and white. They implemented (to much controversy later on) a very effective lossless compression algorithm that allowed the GIF format to produce quality images at lower file sizes.
