Google+What is Google+?
Google+ integrates social service Google Profiles, and introduces new services identified as Circles, Hangouts and Sparks. Google+ is available as a website and on mobile devices. Sources such as The New York Times have declared it Google's biggest attempt to rival the social network Facebook, which has over 800 million users. Google+ is considered the company's fourth foray into social networking, following Google Buzz (launched 2010, retired in 2011), Google Friend Connect (launched 2008, to be retired by March 2012) and orkut (launched in 2004, now operated entirely by subsidiary Google Brazil).
