Back in 2011, Naruto was just an anonymous macaque in the jungles of Indonesia. On one particular day, however, the photogenic primate happened upon a wildlife photographer's camera and snapped a "monkey selfie."
Whether the act was intentional or a quite-too-literal instance of monkeying around, only the grinning primate knows for certain. But it raised a complicated question: Who owns the images Naruto took, the monkey or the man?
It also started a years-long saga in which the U.S. Copyright Office and even Wikipedia weighed in.
