Yahoo! Messenger (sometimes abbreviated Y!M) was an instant messaging client and associated protocol created and formerly operated by Yahoo!. Yahoo! Messenger was provided free of charge and could be downloaded and used with a generic "Yahoo ID", which also allowed access to other Yahoo! services, such as Yahoo! Mail. The service also offered VoIP, file transfers, webcam hosting, a text messaging service, and chat rooms in various categories. In addition to instant messaging features similar to those offered by ICQ, it also offered (on Microsoft Windows) features such as: IMVironments (customizing the look of Instant Message windows, some of which include authorized themes of various cartoons such as Garfield or Dilbert), address-book integration and Custom Status Messages. It was also the first major IM client to feature BUZZing and music-status. Yahoo! Messenger dates back to Yahoo! Chat, which was a public chat room service. The actual client, originally called Yahoo! Pager, launched on March 9, 1998 and renamed to Yahoo! Messenger in 1999. Yahoo! Messenger was among the most popular instant messengers during the 2000s. In 2015, a reworked Yahoo! Messenger service was introduced and the legacy version was discontinued in 2016. The new Yahoo! Messenger itself was shut down entirely on July 17, 2018, after less than three years.
History
Yahoo! Pager Yahoo! Pager launched on March 9, 1998, an instant messaging (IM) client integrated with Yahoo! services including Yahoo! Chat (more explained in its section below). It included basic messaging support, a buddy list with status message support, the ability to block other users, alerts when a buddies came online, and notifications when a new Yahoo! Mail message arrived. In 2000, the name changed to Yahoo! Messenger.
Versions 5 to 8 Version 5.0, released November 2001, introduced IMVironments, an initiative that allowed users to play music and Flash Video clips inside the IM window. Yahoo! partnered with rock band Garbage that provided their single "Androgyny" available to share by users. Other partnerships also made IMVironments for the movie Monsters, Inc., the video game Super Smash Bros. Melee, and the character Hello Kitty, among others. In August 2002 with the release of version 5.5, the resolution for video calling was increased to a possible 320x240 and 20 frames per second (up from 160x120 and 1 frame per second). From October 2002, Yahoo! offered for corporate subscribers a more secure and better (SSL) encrypted IM client, called Yahoo! Messenger Enterprise Edition. It was released with a $30 yearly subscription package in 2003. Yahoo! Messenger version 6.0 was released in May 2004. It added games, music, photos, and Yahoo! Search, alongside a "stealth" mode. It also debuted Yahoo! Avatars. With the release of version 7.0 in August 2005, the client was now renamed to Yahoo! Messenger with Voice. It had several new features such as VoIP, voicemail, drag-and-drop file and photo sharing, Yahoo! 360° and LAUNCHcast integration, and others. It was seen as a challenger against Skype. On October 12, 2005, Yahoo! and Microsoft formed an alliance in which Yahoo! Messenger and MSN Messenger (later known as Windows Live Messenger) will be interconnected, allowing users of both communities to communicate and share emoticons and buddy lists with each other. The service was enabled on Yahoo! Messenger with Voice 8.0 in July 2006. As of version 8.1, the name switched back to just Yahoo! Messenger. Beginning in 2006, Yahoo made known its intention to provide a web interface for Yahoo! Messenger, culminating in the Gmail-like web archival and indexing of chat conversations through Yahoo! Mail. However, while Yahoo! Mail integrated much of the rudimentary features of Messenger beginning in 2007, Yahoo did not succeed initially in integrating archival of chat conversations into Mail. Instead, a separate Adobe Flex-based web messenger was released in 2007 with archival of conversations which take place inside the web messenger itself.
Web version and later releases
At the Consumer Electronics Show in January 2007, Yahoo! Messenger for Vista was introduced, which is a version designed and optimized for Windows Vista. It exploited the new design elements of Vista's Windows Presentation Foundation (WPF) and introduced a new user interface and features. The application was in a preview beta until finally released for download on December 6, 2007. As of October 24, 2008, Yahoo! Messenger for Vista is no longer available. In May 2007, Yahoo! Messenger for the Web was launched, a browser-based client of the IM service. Yahoo! Messenger version 9 was released in September 2008. It allows the viewing of YouTube videos within the chat window, and integrates with other Yahoo! services such as Flickr. This version also saw the release of Pingbox, which embeds on a blog or website and allows visitors to send IM texts anonymously without needing Yahoo! Messenger software or to sign in. Version 10, released November 2009, incorporates many bug fixes and features high-quality video calling. The last major Windows client release, version 11 in 2011, featured integration with Facebook, Twitter and Zynga, allowing chat with Facebook friends and playing Zynga games within. It also archives past messages on an online server which is accessible through the client. Version 11.5 (released November 2011) added tabbed IMs.
New Yahoo Messenger
In December 2015, an all-new, rewritten Yahoo! Messenger was launched, only on mobile and through a browser. A desktop version of the "new" Messenger was later released, shortly before the "legacy" Messenger shut down on August 5, 2016 and the clients no longer working by August 31, 2016. Unable to find success like in the older days, Yahoo! eventually announced that the new Yahoo! Messenger service would shut down on July 17, 2018.
