Instant messaging (IM) technology is a type of online chat allowing immediate transmission of messages over the Internet or another computer network. Messages are typically transmitted between two or more parties, when each user inputs text and triggers a transmission to the recipient(s), who are all connected on a common network.[1] It differs from email in that conversations over instant messaging happen in real-time (hence "instant"). Most modern IM applications (sometimes called "social messengers", "messaging apps", "chat apps" or "chat clients") use push technology and also add other features such as emojis (or graphical smileys), file transfer, chatbots, voice over IP, or video chat capabilities.
Instant messaging applications can store messages with either local-based device storage (e.g. WhatsApp, Viber, Line, WeChat, Signal etc.) or cloud-based server storage (e.g. Telegram, Skype, Facebook Messenger, Google Meet/Chat, Discord, Slack etc.).
Instant messaging was pioneered in the early Internet era; the IRC protocol was the earliest to achieve wide adoption.[2] Later in the 1990s, ICQ was among the first closed and commercialized instant messengers, and several rival services appeared afterwards as it became a popular use of the Internet.[3] Beginning with its first introduction in 2005, BlackBerry Messenger, which initially had been available only on BlackBerry smartphones, soon became one of the most popular mobile instant messaging apps worldwide. BBM was for instance the most used mobile messaging app in the United Kingdom[4] and Indonesia.[5] Instant messaging remains very popular today; IM apps are the most widely used smartphone apps: in 2018 there were over 50 million Signal users, 980 million monthly active users of WeChat and 1.3 billion monthly users of WhatsApp Messenger.
Instant messaging is a set of communication technologies used for text-based communication between two (private messaging) or more (chat room) participants over the Internet or other types of networks (see also LAN messenger).[6] IM chats happen in real-time. Online chat and instant messaging differ from other technologies such as email due to the perceived quasi-synchrony of the communications by the users, although some systems allow users to send offline messages that the other user receives when logging in.[7]
IM allows effective and efficient communication, allowing immediate receipt of acknowledgment or reply. However IM is basically not necessarily supported by transaction control. In many cases, instant messaging includes added features which can make it even more popular. For example, users may see each other via webcams, or talk directly for free over the Internet using a microphone and headphones or loudspeakers. Many applications allow file transfers, although they are usually limited in the permissible file-size.[8] It is usually possible to save a text conversation for later reference. Instant messages are often logged in a local message history, making it similar to the persistent nature of emails.
Non-IM types of chat include multicast transmission, usually referred to as "chat rooms", where participants might be anonymous or might be previously known to each other (for example collaborators on a project that is using chat to facilitate communication).
An instant message service center (IMSC) is a network element in the mobile telephone network which delivers instant messages. When a user sends an IM message to another user, the phone sends the message to the IMSC. The IMSC stores the message and delivers it to the destination user when they are available. The IMSC usually has a configurable time limit for how long it will store the message. Few companies who make many of the IMSCs in use in the GSM world are Miyowa, Followap and OZ. Other players include Acision, Colibria, Ericsson, Nokia, Comverse Technology, Now Wireless, Jinny Software, Miyowa, Feelingk and few others.
The term "Instant Messenger" is a service mark of Time Warner and may not be used in software not affiliated with AOL in the United States.[11] For this reason, in April 2007, the instant messaging client formerly named Gaim (or gaim) announced that they would be renamed "Pidgin".[12]
Modern IM services generally provide their own client, either a separately installed piece of software, or a browser-based client. They are normally centralised networks run by the servers of the platform's operators, unlike peer-to-peer protocols like XMPP. These usually only work within the same IM network, although some allow limited function with other services. Third party client software applications exist that will connect with most of the major IM services. There is the class of instant messengers that uses the serverless model, which doesn't require servers, and the IM network consists only of clients. There are several serverless messengers: RetroShare, Tox, Bitmessage, Ricochet, Ring.
Some examples of popular IM services today include Signal, Telegram, WhatsApp Messenger, WeChat, QQ Messenger, Viber, Line, and Snapchat.[citation needed] The popularity of certain apps greatly differ between different countries. Certain apps have emphasis on certain uses - for example Skype focuses on video calling, Slack focuses on messaging and file sharing for work teams, and Snapchat focuses on image messages. Some social networking services offer messaging services as a component of their overall platform, such as Facebook's Facebook Messenger, who also own WhatsApp. Others have a direct messaging function as an additional adjunct component of their social networking platforms, like Instagram, Reddit, Tumblr, TikTok, Clubhouse and Twitter, either directly or through chat rooms.
Private chat allows private conversation with another person or a group. The privacy aspect can also be enhanced in a number of ways such as end to end encryption by default like Signal. Or some applications have a timer feature, like Snapchat, where messages, conversations or files such as photos are automatically deleted from the users phone once the time limit is reached. Public and group chat features allow users to communicate with multiple people at a time.
Many major IM services and applications offer the call feature for user-to-user calls, conference calls, and voice messages. The call functionality is useful for professionals who utilize the application for work purposes and as a hands-free method. Videotelephony using a webcam is also possible by some.
Some IM applications include in-app games for entertainment. Yahoo! Messenger for example introduced these where users could play a game and viewed by friends in real-time.[13] The Messenger application has a built in option to play computer games with people in a chat, including games like Tetris and Blackjack.
Though a relatively new feature, peer-to-peer payments are available on major messaging platforms. This functionality allows individuals to use one application for both communication and financial tasks. The lack of a service fee also makes messaging apps advantageous to financial applications. Major platforms such as Facebook messenger and WeChat already offer a payment feature, and this functionality is likely to become a standard amongst IM apps competing in the market.
Though the term dates from the 1990s, instant messaging predates the Internet, first appearing on multi-user operating systems like Compatible Time-Sharing System (CTSS) and Multiplexed Information and Computing Service (Multics)[14][15] in the mid-1960s. Initially, some of these systems were used as notification systems for services like printing, but quickly were used to facilitate communication with other users logged into the same machine. CTSS facilitated communication via text message for up to 30 people.[16]
Parallel to instant messaging were early online chat facilities, the earliest of which was Talkomatic (1973) on the PLATO system, which allowed 5 people to chat simultaneously on a 512 x 512 plasma display (5 lines of text + 1 status line per person). During the bulletin board system (BBS) phenomenon that peaked during the 1980s, some systems incorporated chat features which were similar to instant messaging; Freelancin' Roundtable was one prime example. The first[17] such general-availability commercial online chat service (as opposed to PLATO, which was educational) was the CompuServe CB Simulator in 1980,[18] created by CompuServe executive Alexander "Sandy" Trevor in Columbus, Ohio.
As networks developed, the protocols spread with the networks. Some of these used a peer-to-peer protocol (e.g. talk, ntalk and ytalk), while others required peers to connect to a server (see talker and IRC). The Zephyr Notification Service (still in use at some institutions) was invented at MIT's Project Athena in the 1980s to allow service providers to locate and send messages to users.
Early instant messaging programs were primarily real-time text, where characters appeared as they were typed. This includes the Unix "talk" command line program, which was popular in the 1980s and early 1990s. Some BBS chat programs (i.e. Celerity BBS) also used a similar interface. Modern implementations of real-time text also exist in instant messengers, such as AOL's Real-Time IM[19] as an optional feature.[20]
In the latter half of the 1980s and into the early 1990s, the Quantum Link online service for Commodore 64 computers offered user-to-user messages between concurrently connected customers, which they called "On-Line Messages" (or OLM for short), and later "FlashMail." Quantum Link later became America Online and made AOL Instant Messenger (AIM, discussed later). While the Quantum Link client software ran on a Commodore 64, using only the Commodore's PETSCII text-graphics, the screen was visually divided into sections and OLMs would appear as a yellow bar saying "Message From:" and the name of the sender along with the message across the top of whatever the user was already doing, and presented a list of options for responding.[21] As such, it could be considered a type of graphical user interface (GUI), albeit much more primitive than the later Unix, Windows and Macintosh based GUI IM software. OLMs were what Q-Link called "Plus Services" meaning they charged an extra per-minute fee on top of the monthly Q-Link access costs.
