Yahoo! Messenger

Yahoo! Messenger (sometimes abbreviated Y!M) was an advertisement-supported instant messaging client and associated protocol provided 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. 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. The chat room service shut down in 2012. 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. A new Yahoo! Messenger was released in 2015, replacing the older one. Yahoo! Messenger was shut down entirely on July 17, 2018, replaced by a new service titled Yahoo! Together, only to be shut down as well in 2019. Yahoo! Messenger offered file sending capabilities to its users. Files could be up to 2 GB each. After the software's relaunch, only certain media files could be shared: photos, animated GIFs and videos. It also allowed album sharing, with multiple media files in one IM. The animated GIF feature integrated with Tumblr, also owned by Yahoo! at that time. The new Yahoo! Messenger added a like button to messages and media. It was basic in functionality, adding a heart when clicked and listing contacts who added a like. The new Yahoo! Messenger allowed messages to be unsent, deleting them from both the sender and the receiver's messaging page. The new Yahoo! Messenger allowed private group conversations.
