Yet while dictating this mission, Lick did not prejudge the right components to achieve it, instead establishing a network of "coopetitive" research labs, each experimenting and racing to develop prototypes of different components of these systems that could then be standardized in interaction with each other and spread across the network. Private sector collaborators played important roles in contributing to this development, including Bolt Beranek and Newman (where Lick served as Vice President just before his role at IPTO and which went on to build a number of prototype systems for the internet) and Xerox PARC (where many of the researchers Lick supported later assembled and continued their work, especially after federal funding diminished). Yet, as is standard in the development and procurement of infrastructure and public works in a city, these roles were components of an overall vision and plan developed by the networked, multi-sectoral alliance that constituted ARPANET. Contrast this with a model primarily developed and driven in the interest of private corporations, the basis for most personal computing and mobile operating systems, social networks, and cloud infrastructures.
