Parklife and the public: 40 years of personalization in the United Kingdom.

This article historicises practices called 'personalization' in the UK. It presents data from interviews with practitioners to show how business leaders, public sector managers, policy analysts, activists and others have crafted their personalizing practices through commercial and governmental work over a 40-year period. These public histories are illuminated by professional biographies, which reveal common interests in the transfer and application of technology, data and data analytics. Yet they also illuminate attempts to reform bureaucracies in public and private sectors alike during the late 20th and early twenty-first century. The article asks how mobility - of professionals and their personalizing practices - has affected the pre-existing contrast between, and separation of, public and private organizations. This article contributes to commentaries on personalization that view it as an essentially private and privatizing process. What remains of such domains once they have been crossed, and from whose perspective? This UK history raises questions for comparative histories of personalization and its synonyms elsewhere.
