Incorporated in 1989, ACD Systems Ltd. evolved into a software developer for the nascent CD-ROM cataloguing industry. It was realized that a key technological advantage could be found if ACD provided the fastest software JPEG decoder on the market. After intensive research and development, ACDSee was born and quickly evolved into the dominant player in the image viewing and management market. ACDSee was bundled with and became the defacto JPEG decoder/viewer for Mosaic, the very first Web browser. As a shareware program ACDSee quickly dominated the worldwide web and has since built an impressive global user base estimated to be well over 25 million users.
