Interestingly enough, that is actually relatively around the first time I ever heard of a "selfie". I was in college and it was sometime between 2004 and 2006. I distinctly remember selfies were considered a bit cringey at first. Of course society would eventually embrace the selfie, but this was still before the smart phone.
Here is the picture of the first known selfie in history, his name is Robert Cornelius (1809-1893)
Selfies is nothing new people have been doing it at least since 1839, they just did not call it selfie as we have done for the last what 20 years or something
Even before photography artists painted self-portraits.
Yeah that`s true, the oldest known painted self-potrait (as far as i know) was done by Jan van Eyck in 1433 called Portrait of a Man. So we can say that self portraits/ selfies has been going on for at least 587 years.
