This article presents an argument for an expansion of fair use, based not on theories of authorship or rights of autonomy but rather on a theory of the audience linked to social practice. The article asks, in essence, whether audiences determine the meaning, purpose, function, or social benefit of an allegedly infringing work, often regardless of what the work’s creator did or intended. If so, does this matter for the purpose of a fair use analysis based on a claim of transformativeness?
