Google Plus (stylized as Google+) is an Internet-based social network that is owned and operated by Google.
The service, Google's fourth foray into social networking, experienced strong growth in its initial years, although usage statistics have varied, depending on how the service is defined. Three Google executives have overseen the service, which has undergone substantial changes leading to a redesign in November 2015.
Google+ is the company's fourth foray into social networking, following Google Buzz (launched 2010, retired in 2011), Google Friend Connect (launched 2008, retired by March 1, 2012), and Orkut (launched in 2004, as of 2013 operated entirely by subsidiary Google Brazil – retired in September 2014).
Google+ launched in June 2011. Features included the ability to post photos and status updates to the stream or interest based communities, group different types of relationships (rather than simply "friends") into Circles, a multi-person instant messaging, text and video chat called Hangouts, events, location tagging, and the ability to edit and upload photos to private cloud-based albums.
According to a 2016 book by a former Facebook employee, some leaders at Facebook saw Google's foray into social networking as a serious threat to the company. Facebook founder Mark Zuckerberg instituted a company-wide "lockdown", signaling that employees were supposed to dedicate time to bringing Facebook's features into line with Google+.
