One of the reasons that R R Donnelley & Sons Co wants to sell all or part of its Stream International software services company is that Stream’s so-called software manufacturing business (though how you can call duplicating software on disks and sticking the disks into boxes manufacturing escapes us) is not doing as well as expected. It serves Microsoft Corp and others and is suffering from slower-than-expected demand, especially for Windows95 – presumably, no-one makes a decision to buy Windows95, they simply find it preloaded on whatever machine they choose to buy. Donnelley is said to be searching for buyers for the unit, which has annual sales of about $600m and has been valued at $250m.
