Xanga began in 1999 as a site for sharing book and music reviews. It became public in 2000, following a series of e-mail recruitment methods via GeoCities. Over the next few years, Xanga underwent several formatting changes. Featured Content was divided in 2002, being replaced by Premium and Classic views. Eventually, new profile features such as friends, "nudges", and chat forums that resemble Facebook were added, and video and audio capability were added in 2006. According to Alexa Internet, an internet metrics website, Xanga's ranking peaked in 2007 and has fallen continually since that date.
