A selfie is a self-portrait photograph, typically taken with a digital camera or camera phone held in the hand or supported by a so-called selfie stick, which has recently became a popular device.

The earliest usage of the word selfie can be traced as far back as 2002. It first appeared in Karl Kruszelnicki's 'Dr Karl Self-Serve Science Forum', an Australian internet forum (ABC Online) on the 13th of September, 2002.

Nowadays the word "selfie" is widely used both online and in the real life.
