In September 2017, Instagram boasted 500 million daily active users of its self-promotion, selfie-sharing app and 800 million monthly active users.Snapchat reports 178 million daily active users of its service.
However, writer Kate Losse recounts that between 20 (when Facebook became more popular than My Space), the "My Space pic" (typically "an amateurish, flash-blinded self-portrait, often taken in front of a bathroom mirror") became an indication of bad taste for users of the newer Facebook social network.
Early Facebook portraits, in contrast, were usually well-focused and more formal, taken by others from distance.
The debut of the portable Kodak Brownie box camera in 1900 led to photographic self-portraiture becoming a more widespread technique.
The method was usually by mirror and stabilizing the camera either on a nearby object or on a tripod while framing via a viewfinder at the top of the box.
Many selfies are intended to present a flattering image of the person, especially to friends whom the photographer expects to be supportive.
However, a 2013 study of Facebook users found that posting photos of oneself correlates with lower levels of social support from and intimacy with Facebook friends (except for those marked as Close Friends).
Grand Duchess Anastasia Nikolaevna of Russia, at the age of 13, was one of the first teenagers to take her own picture using a mirror to send to a friend in 1914.
In the letter that accompanied the photograph, she wrote, "I took this picture of myself looking at the mirror.
It was very hard as my hands were trembling." Photographic self-portraiture flourished in the 1970s when affordable instant cameras birthed a new medium of self-expression, capturing uncharacteristically personal insight into otherwise conservative individuals This practice transitioned naturally across to digital cameras as they supplanted film cameras around the turn of the millennium.
The first known use of the word selfie in any paper or electronic medium appeared in an Australian internet forum on 13 September 2002.
As of July 2017, in order of popularity, the four most popular social networking services are Facebook, Facebook Messenger, Instagram, and Snapchat.
