Yahoo! Messenger (sometimes abbreviated Y!M ) is an advertisement-supported instant messaging client and associated protocol provided by Yahoo!. Yahoo Messenger is provided free of charge and can be downloaded and used with a generic "Yahoo ID" which also allows access to other Yahoo! services, such as Yahoo! Mail, where users can be automatically notified when they receive new email. Yahoo! also offers PC-to-PC, PC-to-Phone and Phone-to-PC service, file transfers, webcam hosting, text messaging service, and chat rooms in various categories. Yahoo! Messenger was originally launched under the name Yahoo! Pager on March 9, 1998. In addition to instant messaging features similar to those offered by ICQ, it also offers (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. Another recently added feature is customized avatars. Yahoo Messenger also allows users to access Yahoo Chat Rooms. As of December 14, 2012, all public chat rooms on Yahoo Messenger have been shut down as part of a series of features being changed/added/deleted. As of March 27, 2016, the only supported clients are the Android, iOS and web browser clients. The original Windows, Mac, Linux and Solaris clients are not supported anymore, and their servers began shutting down on August 5, 2016, with the clients no longer working by August 31, 2016. It turned out that the servers for the legacy clients were finally shut down sometime between the mid-morning and early afternoon hours east coast time on September 1, 2016, resulting in the legacy desktop clients no longer being able to access their buddy/contact lists. On April 12, 2016, Yahoo announced that the messenger would support six non-English languages to bridge the language gap and create personalised experiences for its users. Yahoo Messenger will support Hindi (on Android devices only), Chinese, French, German, Spanish and Indonesian. A new desktop version for Windows and Mac has been released. Yahoo Messenger will no longer be supported after July 17, 2018.
