Google plus

Google+ (Google Plus) is a multilingual social networking and identity service owned and operated by Google Inc. It is the second- largest social networking site in the world. It has approximate 359 million active users. As of May 2013, it had a total of 500 million registered users, of whom 235 million are active in a given month.

Google launched the Google+ service as an invitation- only “field test” on June 28, 2011, but soon suspended early inviters due to an “insane demand” for new accounts. On August 6, each Google+ member had 150 invitations to give out September 20, 2011, when Google+ opened to everyone 18 years of age or older without the need for an invitation. Google+ is an available as a website and on mobile devices. In the “Stream”, this occupies the middle of three columns on the page; users see updates from those in their Circles. There is an input box which allows users to enter a post. Along with the text entry field there are icons to upload and videos. “Circles” enable users to organize people into groups for sharing across various Google products and services.

Although other users may be users may be able to view a list of people in a user’s collection of Circles, they cannot view the names of those Circles. “Hangouts” are places used to facilitate group video chat (with a maximum of 10 people participating in a single Hangout at any point in time). Only Google+ users can join the “Hangout” if they happen to possess the unique URL of the Hangout.
“Messenger” is a feature available to Android, I Phone, and SMS devices for communicating through instant messaging within Circles.

“Instant Upload” is specific to mobile devices; it stores photos or videos in a private album for sharing later.
“Data Liberation” option provides the ability to download one’s content from Google+. “Search in Google+” allows users to search for content within Google+. Users type what they’re looking for into the Google+ search box, and Google+ will return relevant people and posts, as well as popular content from around the web.
