2011年6月29日，Google正式開放試驗Google+服務，這是創辦人[[拉里·佩奇]]成為新執行長後的重大任務，该服务整合了Google的所有社交服务（诸如[[Google账户|Google Profiles]]和[[Google Buzz]]），还加入了很多新的功能，比如社交圈（Circles）多人視訊聊天（Hangouts），話題靈感（Sparks），Huddles以及-{zh-cn:移动; zh-hk:流動; zh-tw:行動;}-社交應用（Mobile）<ref name="Official Website">Official Google+ Website http://plus.google.com/ {{Wayback|url=http://plus.google.com/ |date=20120215235515 }}</ref>。

Google+開放仅24天便获得了2000萬名用户，而[[Twitter]]和[[Facebook]]則分別用1035天和1152天才達到2000萬<ref name="Facebook Stats">Facebook, "Statistics". https://www.facebook.com/press/info.php?statistics {{Wayback|url=https://www.facebook.com/press/info.php?statistics |date=20110727200950 }}</ref>用戶數目<ref name="Google+ User Number">{{cite web|url=http://www.techabouts.com/20-million-people-google-2/|title=More 20 Million People Use Google+|accessdate=2011-07-23|deadurl=yes|archiveurl=https://web.archive.org/web/20110923091649/http://www.techabouts.com/20-million-people-google-2/|archivedate=2011-09-23}}</ref>。据称这是Google挑战社交网络竞争对手[[Facebook]]最有野心的一次企图<ref name="New York Times article">The New York Times, "Another Try by Google to Take On Facebook", 28 June 2011 http://www.nytimes.com/2011/06/29/technology/29google.html?_r=1 {{Wayback|url=http://www.nytimes.com/2011/06/29/technology/29google.html?_r=1 |date=20110701150302 }}</ref>，Facebook在2010年已经有超過五億每月登入用户。Google+針對Facebook過於開放的缺點，以隱私功能作為區分點，讓用戶可以在不同的朋友圈裏分享資訊。Google+的圈子功能，能把好友分成不同的群組，分別傳送不同的訊息，也正中了Facebook的弱點，目前Facebook需要透過繁複的設定才能把線上好友分成不同群組。Google+還提供視訊聊天功能，最多支持10人的電話會議<ref name="Google+ Stream">{{cite web|url=http://searchengineland.com/googles-facebook-competitor-the-google-social-network-finally-arrives-83401|title=Google’s Facebook Competitor, The Google+ Social Network, Finally Arrives|accessdate=2011-06-29|archive-url=https://web.archive.org/web/20110629131747/http://searchengineland.com/googles-facebook-competitor-the-google-social-network-finally-arrives-83401|archive-date=2011-06-29|dead-url=no}}</ref>。Google+開放的第一日，由於過多使用者被邀請加入，引致Google開放當天就關閉了使用者的邀請功能。

在2013年一月歷經多次改版後，超越Twitter，一度成為世界上第二大的社交網站<ref>{{cite web|url=http://www.leiphone.com/google-plus-active-user.html|title=Google+成全球第二大社交网络 仅次于FB|accessdate=2013-06-24|work=雷锋网|date=2013-01-27|language=zh-hans|archive-url=https://web.archive.org/web/20130503164752/http://www.leiphone.com/google-plus-active-user.html|archive-date=2013-05-03|dead-url=no}}</ref>。

2018年10月，Google承認由於軟體漏洞，Google+可能有多達50萬名用戶的個人資料洩漏給外部開發商，且早於2018年3月發現漏洞後，公司內部開會決定，不把這件事通知用戶，避免聲譽受損，或成為監管機構的針對對象<ref>{{cite web|url=https://tw.appledaily.com/new/realtime/20181009/1444249/|title=洩50萬用戶個資竟還隱匿　谷歌宣布關閉Google+|publisher=台灣蘋果日報|date=2018-10-09|quote=Google內部人員則在今年3月發現漏洞後作出補救，不過公司內部開會決定，不把這件事通知用戶，避免聲譽受損，或成為監管機構的針對對象。Google當時向管理層分析，如果對外公布相關消息，令監管機構Google愈來愈對有興趣，甚至可能成為臉書的「劍橋分析洩密事故」翻版。|access-date=2018-10-09|archive-url=https://web.archive.org/web/20190216064100/https://tw.appledaily.com/new/realtime/20181009/1444249/|archive-date=2019-02-16|dead-url=no}}</ref><ref>{{cite web|url=https://www.washingtonpost.com/technology/2018/10/08/google-overhauls-privacy-rules-after-discovering-exposure-user-data/?noredirect=on&utm_term=.c311c70a7862|title=Google for months kept secret a bug that imperiled the personal data of Google+ users|author1=Craig Timberg|author2=Renae Merle|author3=Cat Zakrzewski|date=2018-10-08|quote=Google discovered the Google+ security bug in the same month that Silicon Valley rival Facebook was facing massive scrutiny over its role in allowing people affiliated with political consultancy Cambridge Analytica to collect data on 87 million users — an incident that led to demands that Facebook chief executive Mark Zuckerberg testify on Capitol Hill.|publisher=The Washington Post|access-date=2018-10-09|archive-url=https://web.archive.org/web/20181009092914/https://www.washingtonpost.com/technology/2018/10/08/google-overhauls-privacy-rules-after-discovering-exposure-user-data/?noredirect=on&utm_term=.c311c70a7862|archive-date=2018-10-09|dead-url=no}}</ref>。

2019年2月3日，因為其使用者參與度低，加上先前发现的可能會導致數十萬名的使用者資料外洩潛在的軟體錯誤<ref name="wall street journal">{{cite web|url=https://www.wsj.com/articles/google-exposed-user-data-feared-repercussions-of-disclosing-to-public-1539017194|title=Google Exposed User Data, Feared Repercussions of Disclosing to Public|work=The Wall Street Journal|date=2018-10-08|first1=Douglas|last1=MacMillan|first2=Robert|last2=McMillan|accessdate=2018-10-08|subscription=yes|language=en-US|issn=0099-9660|archive-url=https://web.archive.org/web/20181008170012/https://www.wsj.com/articles/google-exposed-user-data-feared-repercussions-of-disclosing-to-public-1539017194|archive-date=2018-10-08|dead-url=no}}</ref>，Google宣佈2019年4月2日他們將會關閉个人版的Google+。个人用户可以在关闭前下載並遷移他們的資訊，不過企業版保留<ref name="project strobe">{{cite web|url=https://www.blog.google/technology/safety-security/project-strobe/|title=Project Strobe: Protecting your data, improving our third-party APIs, and sunsetting consumer Google+|first=Ben|last=Smith|date=2018-10-08|accessdate=2018-10-08|work=Google|archive-url=https://web.archive.org/web/20181008172414/https://www.blog.google/technology/safety-security/project-strobe/|archive-date=2018-10-08|dead-url=no}}</ref><ref>{{Cite web|url=https://www.blog.google/technology/safety-security/expediting-changes-google-plus/|title=Expediting changes to Google+|last=Thacker|first=David|date=2018-12-10|website=Google: The Keyword (company blog)|language=en|archive-url=https://web.archive.org/web/20181210233906/https://www.blog.google/technology/safety-security/expediting-changes-google-plus/|archive-date=2018-12-10|dead-url=yes|access-date=2018-12-11}}</ref>，并更名为[[Google Currents]]<ref name="cc">{{Cite web |url=https://techcrunch.com/2019/04/10/whats-left-of-google-is-now-called-currents/ |title=What’s left of Google+ is now called Currents |access-date=2019-04-12 |archive-url=https://web.archive.org/web/20190412130142/https://techcrunch.com/2019/04/10/whats-left-of-google-is-now-called-currents/ |archive-date=2019-04-12 |dead-url=no }}</ref>。
