Google+ was an Internet-based social network owned and operated by Google. The network was launched on June 28, 2011 in the attempt to challenge other social networks and for a time linked other Google products like Blogger and YouTube. The service, Google's fourth foray into social networking, experienced strong growth in its initial years, although usage statistics varied, depending on how the service was defined. Three Google executives oversaw the service, which underwent substantial changes that led to a redesign in November 2015.
Due to low user engagement and disclosed software design flaws that potentially allowed outside developers access to personal information of its users, the Google+ developer API was discontinued on March 7, 2019 and Google+ was shut down for business use and consumers on April 2, 2019.
