Yahoo Messenger

Yahoo Messenger is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Yahoo Messenger rather than just read about it. In short: Yahoo! Messenger (sometimes abbreviated Y!M) was an instant messaging client and associated protocol created and formerly operated by Yahoo!.

Key takeaways

  • Yahoo Messenger belongs to computer science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Yahoo Messenger to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Yahoo Messenger from memory before moving on to harder problems.

Reference excerpt

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.

Worked examples

Example 1 — a first encounter with Yahoo Messenger

Start with the simplest possible case. Write down what Yahoo Messenger claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Yahoo Messenger before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Yahoo Messenger ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Yahoo Messenger

In research
Yahoo Messenger appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Yahoo Messenger in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Yahoo Messenger is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1998 software, Android (operating system) software, BlackBerry software, so understanding it makes those chapters shorter.
In everyday life
Look for Yahoo Messenger outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
