The Xerox Corporation has devised several strategies for managing the numerous spin-off firms that independently commercialized many of its technologies. From 1979 to 1998, thirty-five technology-based organizations emerged from Xerox's research centers. Contradicting the common perception that Xerox “fumbled the future” by letting its technology walk out the door, in fact the company set in motion a series of deliberate initiatives to manage its spin-off organizations. After initially adopting a laissez-faire approach, the company soon turned to ad hoc methods, which evolved into a formal internal venture capital structure and culminated in a triage process, with the result that only companies perceived by Xerox as fitting into its overall corporate strategy were retained. By using spin-offs to withdraw gracefully from areas it considered to be marginal, Xerox for feited the potential to realize value from their research. Some, but not all, of the spin-offs obtained venture capital financing from outside sources and thus prospered independently. Their success demonstrated the opportunity that Xerox missed in managing its spin-offs.
