In the year 2000, only a quarter of the world's recorded information existed in digital format. In just 13 years, this figure rose to 98%. Digital spaces, still largely optional at the beginning of the century, have since taken a central place in human activity - including cultural life. In this digital world, socionumerical spaces (i.e., social networks) have become a phenomenon in their own right, with a penetration rate of 80.3 % of the French population - 52.60 million active users in January 2022 - compared to 58.4 % worldwide (We Are Social, Hootsuite, 2022). In this context, a true process of *"datafication"*¹ is unfolding - with still largely unsuspected implications: "no longer digitising documents, but every aspect of life." The episode "Data brokers, les courtiers de nos données" from the France Inter programme Tout est numérique (7 July 2018) illustrates the extent of the trade built around the data we scatter at every moment of our digital lives - particularly by data brokers. These brokers specialise in collecting, purchasing, and selling data on individuals or organisations. Such data encompasses a wide range of information, from demographic profiles to consumer behaviour, web browsing habits, financial records, and purchase histories. Data brokers acquire this information through public sources, such as government registries, electoral rolls, and publicly available social media data, as well as through commercial sources like transaction records, loyalty programmes, and customer satisfaction surveys. In addition, they gather digital data via cookies, mobile apps, websites, and social media platforms. This massive datafication process carries within it a powerful ideological underpinning. As New York Times columnist Jeff Brookes put it: the belief that "everything that can be measured should be," and that data might even enable us to do something as remarkable as "predict the future."
