A selfie is a self-portrait, typically a photograph, that is posted online. The most common places for selfies are blogs, social networking sites, such as Facebook, and photo-sharing websites, such as Instagram.
The number of self-portrait photos online has grown rapidly as a function of the simultaneous growth of social networking and smartphone use. Another factor is the inclusion of self-facing cameras on many phones and tablets, which make it very easy for users to take their own photographs.
As of June 2013, #me is the third-most common hashtag on Instagram, after #instagood (2) and #love (1). An Instagram search yielded 51 million photos with the hashtag #me, and another 23 million tagged as #selfie.
Designer/photographer Jim Krause is said to have coined "selfie" in 2005, and Time magazine named the term one of its top 10 buzzwords for 2012. The first self-portrait photographs, on the other hand, became possible in the late 1880s, when camera shutters with self-timers became available.
