Snapchat is an online photo sharing application based in Los Angeles. It can also be used to share text and films. The sender can determine how long the receiver of the message can view what has been sent.
When asked why a time limit (of up to ten seconds) had been imposed on communications, the site's founder's replied that this was to prevent users projecting an idealized or outright fictional version of themselves, thus enabling truer one-to-one communications.
The time limit also means the images or text take up less memory on your device, given they delete themselves after the limit expires.
