This Article explores how the explosive growth of online streaming is transforming the market for creative content. Two decades ago, the popularization of the internet led to what we refer to here as the first digital disruption: Napster, file-sharing, and the re-ordering of numerous content industries, from music to film to news. The advent of mass streaming has led us to a second digital disruption, one driven by the ability of streaming platforms to harvest massive amounts of data about consumer preferences and consumption patterns. Coupled to powerful computing, the data that firms like Netflix, Spotify, and Apple collect allows those firms to know what consumers want in incredible detail. This knowledge has long shaped advertising; now it is beginning to shape the content streaming firms purchase or even produce, a phenomenon we call “data-driven creativity.” This Article explores these phenomena across a range of firms and content industries. In particular, we take a close look at the firm that is perhaps farthest along in its use of data-driven creativity. We show how MindGeek, the little-known parent company of Pornhub and a leader in the market for adult entertainment, has leveraged streaming data not only to organize and suggest content to consumers but even to shape creative decisions. MindGeek is itself the product of the same forces—the shift to digital distribution and the accompanying explosion of free content—that transformed mainstream creative industries and paved the way for the rise of streaming. We first show how the adult industry adapted to the first digital disruption; that story aligns with similar accounts of how creative industries adapt to a loss of control over intellectual property. We then show how MindGeek and other streaming firms such as Netflix, Spotify, and Amazon are leveraging the second digital disruption, using data to make decisions about content promotion, aggregation, dissemination, and investment. Finally, we consider what these trends suggest for competition and innovation in markets for creative work. By making creative production far less risky, data-driven creativity may drive down the need for strong IP rights and reshape conventional assumptions about the purpose and role of IP. At the same time, the rise of data-driven creativity may reinforce the tendency of online markets toward dominance by a few major firms, with significant implications for competition and innovation.
