Markets for information technology products such as computers and operating systems are characterized by significant externalities. Research in economics shows that markets characterized by externalities often come to be dominated by few (often single) products (which may or may not be technically superior). Such domination threatens technological diversity, which, this paper argues, is valuable to users of computing. The paper suggests actions by IS managers that support diversity in the face of market dynamics favoring concentration.
