Google+

Google+ is a multilingual social networking and identity service owned and operated by Google Inc. It was launched in June 28, 2011. As of September 2012, it has a total of 400 million registered users of whom 100 million are active on a monthly basis. Unlike other conventional social networks which are generally accessed through a single website, Google has described Google+ as a "social layer" consisting of not just a single site, but rather an overarching "layer" which covers many of its online properties.

On September 20, 2011, Google+ was opened to everyone 18 years of age or older without the need for an invitation. It was opened for a younger age group (13+ years old in US and most countries, 14+ in South Korea and Spain, 16+ in the Netherlands) on January 26, 2012.
