The concept of the selfie dates back at least as far as the first post-invention-of-the-mirror artist who thought to paint a self-portrait. But as a cultural phenomenon, self-shot portraits are rooted in the early days of MySpace, when teens with emo bangs flooded their profiles with headshots taken from just about every conceivable angle.
