Resumen: In recent years, the term `fake news¿ has become popular as a paradigm of mis- and disinformation. The term tends to put this phenomenon within the framework of media organizations. However, the problem is more complex, since it also involves other entities dedicated to deliberately producing and spreading falsehoods, as well as social networks and large internet platforms that work as global carriers of such misleading content. This chapter analyzes the evolution of disinformation in this expanded framework, contextualizing the production, dissemination and consumption of deceptive content beyond the media. Drawing upon a historical review of the mis- and disinformation phenomena over the last few centuries, it examines the more recent transformation experienced by purposefully false content on the internet and big data ecosystem.
