Despite being a new term, ‘fake news’ has evolved rapidly. This paper argues that it should be reserved for cases of deliberate presentation of false or misleading claims as news, where these are misleading by design.

This prospective definition is then tested: first, by contrasting fake news with other forms of public (...) disinformation; second, by considering whether it helps pinpoint conditions for the proliferation of fake news.
