'''Google Talk''' was an [[Instant messaging|instant messaging service]] that provided both text and voice communication.<ref name="googtalk">{{cite web |url=https://www.google.com/talk/about.html |title=Google Talk - About |access-date=January 3, 2010 |archive-url=https://web.archive.org/web/20130201083255/https://www.google.com/talk/about.html |archive-date=February 1, 2013 }}</ref> The instant messaging service was variously referred to colloquially as '''Gchat''', '''Gtalk''', or '''Gmessage''' among its users.<ref>{{cite web |url=http://observer.com/2012/02/google-says-gchat-is-not-a-word/ |title=Google Says 'Gchat' Is Not a Word |author=Adrianne Jeffries |website=[[The New York Observer]] |date=February 10, 2012}}</ref>

Google Talk was also the name of the client applications previously offered by [[Google]] to use the service.

==Features==
===Product integration===
Google Talk was integrated into Gmail where users could send instant messages to other Gmail users. As it worked within a browser, the Google Talk client did not need to be downloaded to send instant messages to Gmail users.

Conversation logs were automatically saved to a "Chats" area in the user's Gmail account. This allowed users to search their chat logs and have them centrally stored in their Gmail accounts. For a long time, it was not possible to directly download chat logs that were not attached to an email conversation,<ref>{{cite web |url=https://groups.google.com/group/Gmail-Help-POP-and-IMAP-en/browse_thread/thread/d69d89a7a52932b2 |title=Download gtalk chat logs with imap. – POP and IMAP |work=Google Groups |access-date=July 18, 2008}}</ref><ref>{{cite web |url=https://groups.google.com/group/Gmail-Help-POP-and-IMAP-en/browse_thread/thread/6274a44e1023de17/02860d89e17adf71?lnk=raot |title=Chats in IMAP (Outlook 2007) – POP and IMAP |work=Google Groups |access-date=July 18, 2008}}</ref> although some workarounds had been found.<ref>{{cite web |url=http://martinml.com/en/how-to-download-and-backup-your-gtalk-gmail-chat-logs/ |title=How to download and backup your GTalk/GMail chat logs |access-date=October 8, 2010}}</ref><ref>{{cite web |url=http://digivorous.blogspot.com/2010/11/how-to-download-and-backup-your.html |title=How to download and backup your GTalk/GMail chat logs – VBScript (Click to run) |access-date=November 6, 2010 |date=November 6, 2010 |archive-date=October 21, 2020 |archive-url=https://web.archive.org/web/20201021103058/http://digivorous.blogspot.com/2010/11/how-to-download-and-backup-your.html |url-status=dead }}</ref> However, on September 15, 2011, Google announced a new feature of its Google Takeout program that allows users to download chat logs via IMAP.<ref>{{cite web |url=http://dataliberation.blogspot.com/2011/09/gmail-liberates-recorded-chat-logs-via.html |title=Gmail Liberates Recorded Chat Logs Via IMAP}}</ref>

Google also integrated Google Talk with [[Orkut]]. This enabled Google Talk users to interact with registered Orkut users, by sending and receiving "scraps" within Orkut. Orkut has since been shut down.

Google Talk Gadget was a web-based module that could be embedded in iGoogle (since discontinued) and other web pages, allowing text chat with users of Google Talk.<ref>{{cite web |url=http://googletalk.blogspot.com/2007/03/google-talk-gadget.html |title=Google Talk Gadget |access-date=February 14, 2012}}</ref> This functionality was at some point{{when|date=June 2018}} discontinued without any real announcement, likely in the face of the release of the [[Google Hangouts]] services.{{citation needed|date=May 2019}}

[[Google+]] was integrated into Google Talk. In the standalone client and the Google Talk widget embedded into Gmail and Google+, Google+ contacts appeared in the contacts list; their respective circles were shown in Google+'s iteration of the widget. Google+ has since been shut down.

===Voice and Video===
It was possible to place and receive phone calls from within Gmail by using Google Talk. In order to receive calls, however, the user had to upgrade to a full [[Google Voice]] account.<ref>{{cite web |title=Upgrading to a full Google Voice account voicemail |url=https://support.google.com/talk/bin/answer.py?hl=en&answer=187927 |access-date=December 14, 2012}}</ref> Initially, users outside of the US could not upgrade to a full Google Voice account or receive phone calls in Gmail.<ref>{{cite web |title=Does making a phone call in Gmail mean I have a Google Voice account? |url=https://support.google.com/talk/bin/answer.py?hl=en&answer=187926 |access-date=December 14, 2012}}</ref> (Outbound calling through Gmail did not require Google Voice and was available in many countries outside the US.)<ref>{{cite news |title=Google Voice Opens Up Outside of the U.S., Now Available in 38 Languages (Updated) |publisher=Time |url=https://techland.time.com/2011/08/03/google-voice-open-outside-u-s-now-available-in-38-languages/ | date=August 3, 2011}}</ref> Google Talk allowed users to leave a voicemail for a contact whether or not they were signed into Google Talk.<ref>{{cite web |title=About Google Talk voicemail |url=https://support.google.com/talk/bin/answer.py?hl=en&answer=44262 |access-date=February 6, 2013 |date=October 16, 2012}}</ref> Messages could be up to 10 minutes long and users could choose to have them sent to their Gmail inbox. Messages could be sent with or without first ringing the recipient's phone number.

Google also provided a Voice and Video Chat browser plugin for Google Talk<ref name="videochat"/> (not to be confused with the standalone Google Talk client) that supported voice and video chat between [[Gmail]] users.<ref name="aboutvideochat">{{cite web|url=http://mail.google.com/support/bin/answer.py?answer=100173|title=About voice and video chat|access-date=November 16, 2008|archive-url=https://web.archive.org/web/20090114195245/http://mail.google.com/support/bin/answer.py?answer=100173|archive-date=January 14, 2009|url-status=dead}}</ref> The plugin was available for Windows (XP, Vista, and 7), [[Mac OS X]] (only on [[Apple–Intel architecture|Intel-based]] Macs),<ref>{{cite web |url=http://mail.google.com/support/bin/answer.py?answer=33540&topic=13292 |archive-url=https://web.archive.org/web/20080228121145/http://mail.google.com/support/bin/?answer=33540&topic=13292 |url-status=dead |archive-date=February 28, 2008 |title=Technical requirements |access-date=February 23, 2009 }}</ref> and [[Linux]] ([[Debian]], Ubuntu, Fedora, and [[OpenSUSE]] packages available, but the binaries worked on other systems).<ref>{{cite web |url=http://gmailblog.blogspot.com/2010/08/use-linux-now-you-can-video-chat-too.html |title=Use Linux? Now you can video chat too |access-date=August 20, 2010}}</ref> The plugin had to be downloaded and installed, but otherwise seamlessly integrated into the Gmail interface.

===Encryption===
The connection between the Google Talk client and the Google Talk server was encrypted, except when using Gmail's chat over HTTP, a [[Federation (information technology)|federated network]] that didn't support encryption, or when using a proxy like IMLogic.{{citation needed|date=September 2013}} End-to-end messages were unencrypted. Some XMPP clients natively supported encryption with Google Talk's servers. It was possible to have end-to-end encryption over the Google Talk network using [[Off-the-Record Messaging|OTR (off-the-record) encryption]] using other chat clients like [[Adium]] (for Mac) or [[Pidgin (software)|Pidgin]] (for Linux and Windows).

Google's version of "Off the Record" was not [[Off-the-Record Messaging|OTR (off-the-record) encryption]].  Enabling "off the record" inside Gmail's Chat turned off logging of messages, but did not enable encryption.

===Offline messaging===
On November 1, 2006, Google introduced offline messaging to Google Talk. This allowed users to send messages to their contacts, even if they were not signed in. They would receive the messages when they next went online even if the user who had sent it was offline. This only worked between Gmail-accounts, not between Google Talk servers and other XMPP servers.<ref>{{Cite web | url=http://googletalk.blogspot.com/2006/11/offline-messages.html | title=Offline messages}}</ref>

===Mobile device compatibility===
On June 30, 2006, Nokia released new software for their [[Nokia 770]] Internet Tablet, that included Google Talk as one of the compatible VoIP clients, because of the XMPP-based software.<ref>{{cite web |url=http://europe.nokia.com/A4144790 |title=Nokia 770 Internet Tablet Support |access-date=November 17, 2007 |archive-url=https://web.archive.org/web/20071029013632/http://europe.nokia.com/A4144790 |archive-date=October 29, 2007 |url-status=dead |df=mdy-all }}</ref> Another Google Talk-compatible device was [[Sony]]'s [[Mylo (Sony)|mylo]], released on September 15, 2006. A Google Talk client was also available for BlackBerry devices from the BlackBerry site.<ref>{{cite web |url=http://www.blackberry.com |title=BlackBerry}}</ref> Google Talk support was also integrated into Google Android devices, but did not support voice and video calls below Android version 2.3.4. This was released in April 2011 for the Google Nexus S.<ref>{{cite web |url=http://googlemobile.blogspot.com/2011/04/video-chat-on-your-android-phone.html |title=Video Chat on Your Android Phone |publisher=Google Mobile Blog}}</ref>

However, given that Google Talk provided XMPP protocol, most mobile phones for which a suitable XMPP client existed<ref>{{cite web |url=http://xmpp.org/xmpp-software/clients/ |title=XMPP Clients}}</ref> could also offer Google Talk service, at least theoretically (depending on the handset, the user may have encounter security warnings because of unsigned [[Java ME]] [[MIDlet]]s or limits put in place by the mobile service provider). Mobile clients specially designed for Google Talk existed as well.<ref>{{cite web |url=http://www.mobileoss.org/p/mgtalk.html |title=Mobile Applications |access-date=November 17, 2007 |archive-url=https://web.archive.org/web/20070406055949/http://www.mobileoss.org/p/mgtalk.html |archive-date=April 6, 2007 |url-status=dead |df=mdy-all }}</ref>

Most phones supported the [[OMA Instant Messaging and Presence Service|IMPS]] protocol, and there was hybrid XMPP/IMPS networks (through [[Extensible Messaging and Presence Protocol|XMPP]] transports, or specially designed hybrid servers),<ref>{{cite web |url=http://www.nowimp.com/ |title=Now IMP Server: Home}}</ref> which could also contact Google Talk users. The Google Talk service itself was unusable from IMPS (that means, one could not log with their Gmail account, but they could talk with their Gmail friends with their IMPS account from their mobile phone).{{Clarify|date=September 2008}}

For most smartphones, including Symbian-based as well as Android, third-party applications such as [[Nimbuzz]] and [[Fring (VoIP)|Fring]] included support for Google Talk accounts, including VoIP calls.

===Text formatting===
Google Talk did not provide the user with a menu for text formatting. Nevertheless, Google Talk did support some text formatting features like making text bold and italic. To write a message in bold, a user could type the required text between two asterisks (*), for example, *this text would be bold in Google Talk*. Similarly for making text italic, one could put text between underscores (_) and for strike-through in text content, one could put text in between dashes (-). This only functioned in some of the Google native tools, and did not always function as expected when received from other XMPP clients.

==History==
[[File:GTLE.png|thumb|A screenshot showing the Google Talk, Labs Edition preview release]]

===2005===
On August 22, 2005, ''[[The New York Times]]'' reported a rumor of a Google-branded "communications tool" service<ref name="NYT">{{cite news |last= Markoff |first= John |author-link= John Markoff |url= https://www.nytimes.com/2005/08/22/technology/22google.html |title= Where Does Google Plan to Spend $4 Billion? |work= The New York Times |access-date= February 1, 2006 |date= August 22, 2005}}</ref> and the ''[[Los Angeles Times]]'' provided details. Subsequently, the [[subdomain]] {{URL|talk.google.com}} was found to have an active XMPP server.<ref name="ActiveServer">{{cite web |year= 2005 |url= http://tomservo.cc/blogs/english/archive/2005/08/22/35.aspx |title= Google IM on XMPP for real? |publisher= Tom Servo's Blogogogogog |access-date= February 1, 2006 |archive-url= https://web.archive.org/web/20060112070025/http://tomservo.cc/blogs/english/archive/2005/08/22/35.aspx <!-- Bot retrieved archive --> |archive-date = January 12, 2006}}</ref> Two methods of logging into the server were discovered soon after and the ensuing response by eager bloggers revealed to numerous others how to log in before the official release by Google.

On the evening of August 23, many logged-in users using [[TCP and UDP port|port]] 5222 to connect were disconnected and unable to log back in. Users using port 5223 to connect were still able to log in, and at 04:12:52 [[UTC]] those users received a broadcast instant message from {{URL|gmail.com}}, an apparently official username used by Google to communicate with their user base, that stated "The broken link has been fixed. Thanks for being our first users!" Port 5222-connectivity was found to have been re-enabled. On August 24, Google Talk was officially launched.

On December 15, 2005, Google released '''libjingle''',<ref>{{cite web |url=https://code.google.com/p/libjingle/ |title=libjingle – Google Talk Voice and P2P Interoperability Library – Google Project Hosting |access-date=February 1, 2012}}</ref> a [[C++]] [[library (computer science)|library]] to implement [[Jingle (protocol)|Jingle]], "a set of extensions to the [[IETF]]'s Extensible Messaging and Presence Protocol (XMPP) for use in voice over IP ([[VoIP]]), video, and other peer-to-peer multimedia sessions."<ref name="Libjingle">{{cite web |year=2005 |url=http://xmpp.org/xsf/press/2005-12-15.shtml |title=Jabber Software Foundation Publishes Open VoIP and Multimedia Protocols |publisher=[[XMPP Standards Foundation]] |access-date=February 1, 2006 |url-status=dead |archive-url=https://web.archive.org/web/20070504093715/http://xmpp.org/xsf/press/2005-12-15.shtml |archive-date=May 4, 2007 |df=mdy-all }}</ref> Libjingle is a library of the code that Google uses for [[peer-to-peer]] communication, and was made available under a [[BSD license]].<ref name="LibjingleNote">{{cite web |last=Beda |first=Joe |year=2005 |url=http://www.eightypercent.net/Archive/2005/12/15.html#a261 |title=libjingle |publisher=EightyPercent.net |access-date=February 1, 2006}}</ref>

===2006===
In 2006, Google reported that they were working on adding new features such as supporting [[Session Initiation Protocol|SIP]] in a future release, which would broaden the userbase for the program.<ref name="SIP">{{cite web|url=https://www.google.com/talk/developer.html#realtime|title=Google Talk and Open Communications – 4. Do you plan to support other real-time communication protocols?|access-date=July 8, 2006}}</ref>

On January 17, 2006, Google enabled [[server-to-server]] communications, [[Federated identity|federating]] itself with any XMPP server that supported the dialback protocol.<ref name="XMMPIntegration">{{cite web |last=Burd |first=Gary |year=2006 |url=http://googletalk.blogspot.com/2006/01/xmpp-federation.html |title=XMPP Federation |publisher=Google Talkabout |access-date=April 3, 2006}}</ref>

On February 7, 2006, [[Gmail]] received chat functionality,<ref>{{cite web |url=https://techcrunch.com/2006/02/07/screen-shots-of-gmail-chat/|title=Screen Shots of Gmail Chat|date=February 7, 2006 }}</ref> using [[Ajax (programming)|Ajax]] for server–browser communication, and was integrated with Google Talk. It also added the ability to chat with a built-in XMPP client. Furthermore, the newly added function led to users nicknaming it GChat.<ref>{{Cite web |last=Gartenberg |first=Chaim |date=2021-06-21 |title=A very brief history of every Google messaging app |url=https://www.theverge.com/2021/6/21/22538240/google-chat-allo-hangouts-talk-messaging-mess-timeline |access-date=2023-07-22 |website=The Verge |language=en-US}}</ref>

In August 2006, Google and eBay announced that they would look into making Google Talk users able to communicate with [[Skype]]: "The companies will also explore interoperability between Skype and Google Talk via open standards to enable [[text chat]] and online presence."<ref name="Skype">{{cite web|url=https://www.google.com/press/pressrel/ebay.html|title=Google and eBay Sign Multi-Year Agreement to Connect Users, Merchants, and Advertisers Around the Globe|publisher=Google Press Center|access-date=December 25, 2006}}</ref> However, with [[Skype#Acquisition by Microsoft|Microsoft's acquisition of Skype]] on May 10, 2011, such interoperability was suspended between Google and eBay.<ref name="MicrosoftAcquisition">{{cite web|url=http://www.webpronews.com/can-skype-help-microsoft-beat-google-2011-05|title=Can Skype Help Microsoft Beat Google?|access-date=May 22, 2010|archive-url=https://web.archive.org/web/20110512010925/http://www.webpronews.com/can-skype-help-microsoft-beat-google-2011-05|archive-date=May 12, 2011|url-status=dead|df=mdy-all}}</ref>

Google integrated Google Talk with [[Orkut]] on November 8, 2006.

===2007===
On March 14, 2007, Google released the Google Talk Gadget, an [[Adobe Flash]]-based Talk module that could be added to iGoogle (formally the Google Personalized Homepage) or embedded in any web page, thus, allowing chat from any operating system which was supported by [[Adobe Flash Player]] as long as [[Adobe Flash Player]] was installed.<ref>{{cite web |url=http://googletalk.blogspot.com/2007/03/google-talk-gadget.html |title=Google Talk Gadget |author=Dudley and Wes Carr |date=March 14, 2007 |work=Google Talkabout |publisher=Google Inc}}</ref>

A screen shot was posted on May 18, 2007, as part of the Google Apps presentation, showing some phone integration in Google Talk.<ref>{{cite web |url=http://googlesystem.blogspot.com/2007/05/phone-calls-in-google-talk.html| title=Phone Calls in Google Talk |publisher=Google Operating System- Unofficial news and tips about Google |access-date=December 7, 2008| date=May 18, 2007 }}</ref> On March 2, 2008. a Google engineer confirmed they had been using it internally for some time.<ref>{{cite web |url=http://googlesystem.blogspot.com/2008/03/google-talk-not-dead-after-all.html |title=Google Talk, Not Dead After All |publisher=Google Operating System- Unofficial news and tips about Google |access-date=December 7, 2008|date=March 2, 2008 }}</ref>

On November 26, 2007, Google Talk released Group Chat capabilities. Before this, users could chat with only one person per window. Group chat allowed many users to chat with each other in an environment similar to [[Internet Relay Chat|IRC]].

On December 6, 2007, Google upgraded its Gmail integrated chat to include [[AOL Instant Messenger]] chat capability. This allowed Gmail users to sign into the AIM chat service and communicate with any AIM user while still being signed on to the Google Talk service. The Google Talk gadget and client had not been upgraded to enable this feature, and no announcement had been made as to when it would be made available.

===2008===
On February 25, 2008, Google added a feature called "Chatback", which allowed a Google Talk account owner to chat with people who did not have one. The account owner first had to create a badge, which could be included in webpages. This badge showed the current availability of the owner. Clicking on the badge resulted in a chat request notification to the owner who could respond by clicking on the specified URL. During the conversation, both parties had to use the Google Talk Gadget and both parties remained anonymous to each other, even the Google Account name of the owner was not revealed to the other peer.

On November 11, 2008, Google Chat (voice and video chat) was launched enabling computer to computer voice and video chat.<ref name="videochat">{{cite web |url=https://www.google.com/chat/video |title=Voice and Video Chat |access-date=April 5, 2011}}</ref> Clues from one of the first [[Google Chrome]] builds in December 2008 suggested that a new Talk client was in the works.<ref>{{cite web |url=https://src.chromium.org/viewvc/chrome?view=rev&revision=6376 |title=Chromium Revision 6376 notes |publisher=The Chromium Authors |access-date=December 7, 2008}}</ref>

Google had a version of Google Talk called Google Talk, Labs Edition, though it lacked many features of Google Talk's other releases.<ref>{{cite web |url=https://www.google.com/talk/labsedition/knownissues.html |title=Top Known Issues |year=2011 |access-date=June 17, 2011 }}</ref>

===2012===
On April 20, 2012, Google announced that it was shutting down the mobile web app for Google Talk.<ref>{{cite web |url=http://googleblog.blogspot.com/2012/04/spring-cleaning-in-spring.html |title=Spring-cleaning … in spring!|date=April 20, 2012 |access-date=February 6, 2013 |quote=We’re shutting down the mobile web app for Google Talk.

In June 2012, Google announced that they were planning to revamp the chat experience by merging Google Talk with Hangouts and Google Messenger to reduce confusion and fragmentation.<ref>{{cite web |url=http://technorati.com/technology/article/googe-plans-to-merge-hangouts-talk/ |title=Googe Plans to Merge Hangouts, Talk & Messenger - Technorati Technology |publisher=Technorati.com |date=June 28, 2012 |access-date=June 14, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20131216191348/http://technorati.com/technology/article/googe-plans-to-merge-hangouts-talk/ |archive-date=December 16, 2013 |df=mdy-all }}</ref>

===2013===
At the Google I/O Conference 2013 Google announced that they were replacing Google Talk, Google+ Messenger and the original Google+ Hangout video chat service with [[Google+ Hangouts]].<ref>{{cite web|url=http://www.ibtimes.co.uk/articles/467943/20130515/google-hangouts-app-io-announcement-ios-android.htm|title=Google Hangouts Takes on BBM and WhatsApp With Free Cross-Platform Messaging|access-date=May 16, 2013|date=May 15, 2013}}</ref>

On May 15, 2013, Google's manager of real-time communication products, Nikhyl Singhal, stated at Google I/O that the move to Google+ Hangouts would mean that XMPP (the protocol that allowed Google Talk to interoperate with other vendors and applications) will not be supported in Hangouts. Mr. Singhal stated that as long as Google Talk was available, 3rd party clients could be expected to continue to work.<ref name="windowspbx201305">{{cite web|url=http://windowspbx.blogspot.com/2013/05/hangouts-wont-hangout-with-other.html|title=Hangouts Won't Hangout With Other Messaging Vendors: Google's New Unified Messaging Drops Open XMPP/Jabber Interop|access-date=May 16, 2013}}</ref>

===2014===
On October 30, 2014, Google announced on their Apps Updates blog that "The Google Talk app for Windows will continue to work for approximately two months before being turned off".<ref name="googleappsupdates.blogspot.com"/>

===2015===
On February 3, 2015, Google sent a system message to users stating, "Google Talk app for Windows will stop working on Feb 16, 2015. It is replaced by the new Hangouts Chrome app."

On February 13, 2015, Google developer Mayur Kamat posted a clarification that XMPP service relied-on by third-party chat apps would continue after the deprecation of the Windows-specific Google Talk client.<ref name="plus.google.com">{{cite web|url=https://plus.google.com/+MayurKamat/posts/ETBvtp9VYav|title=Mayur Kamat - Google+ - Feb 13, 2015|access-date=Feb 17, 2017}}</ref>

After Google officially stopped supporting Google Talk for Windows on February 23, 2015, the application continued to function normally during an apparent grace period lasting until February 28. As of that date, connection attempts returned an error message stating "Username and password do not match." Those users received a notification e-mail stating, in part: "We noticed you recently tried using the Google Talk app for Windows. We wanted to let you know that this was discontinued on February 23rd, 2015. We recommend giving Hangouts a try so you can chat with all your Google contacts."

The Google Talk for Windows application would purportedly still work by connecting through applications using the [[Jabber (IM)|Jabber protocol]] including Pidgin and Gajim but could not connect directly through Google or Gmail.<ref>
