The Pentagon’s recent decision to simplify the updating and revision of its manuals and documents by producing them electronically will generated a potential $2,000m of business, and has sent IBM, Xerox Corp, Eastman Kodak Co, DEC and smaller specialist fry like Xyvision Corp rushing to develop defence based publishing systems: according to the Wall Street Journal, independent estimates suggest that as much as 25% of military documents are out of date at any one time; meanwhile contractors such as McDonnell Douglas charge the Pentagon $300 for each page amended.
