It is questionable just how big the market for optical disk-based image storage and retrieval systems will be – FileNet Corp has been selling the things for six or seven years and has the weight of Ing C Olivetti & Co behind it as an investor, but remains a long way from being an industry heavyweight, and Philips NV has not swept the world with its Megadoc system. Nevertheless, if all your competitors are rushing to embrace the next craze, it takes a lot of nerve to sit on your hands and do nothing. Accordingly, in the next four to six months, ICL Ltd is expected to make its entry into the market with a Unix-based integrated image system, and according to Computer Systems News, will launch in the US at the same time as Europe, with a prime target the law firms that were such big Computer Consoles users.
