CNN reporter Amber Lyon takes an inside look at the hactivist group "Anonymous". Original air date: Jan 14, 2012
The name Anonymous itself is inspired by the perceived anonymity under which users post images and comments on the Internet. Usage of the term Anonymous in the sense of a shared identity began on imageboards.
A tag of Anonymous is assigned to visitors who leave comments without identifying the originator of the posted content. Users of imageboards sometimes jokingly acted as if Anonymous were a real person. As the popularity of imageboards increased, the idea of Anonymous as a collective of unnamed individuals became an internet meme.
