I agree with petersmart, nothing new about it.
Selfie had became a slang word for self-portrait. It had kind of became a new word for when using a smartphone instead of an actual camera to take a photo of self (and usually for the purpose of uploading to social media). Taking self-portrait photographs of yourselves in the mirror have been around for like a hundred of years, since the birth of photography. I can't understand why do people nowadays, when they see an old self-portrait photograph, they goes like "Oh look! An early selfie!" as if the meaning of self-portrait never exist.
But then again, self-portrait already exists long before photography when some people would paint a picture of themselves while looking at a mirror, so in a sense, selfie already exists very, very long before smartphones.
It's old news.
