Instant messaging is a form of text-based real-time communication on the Internet
- “Instant messaging allows you to maintain a list of people that you wish to interact with. You can send messages to any of the people in your list, often called a buddy list or contact list, as long as that person is online. Sending a message opens up a small window where you and your friend can type in messages that both of you can see” - (How Instant Messaging Works retrieved 13:40, 27 May 2006 (MEST))
- “Instant messaging requires the use of a client program that hooks up an instant messaging service and differs from e-mail in that conversations are then able to happen in realtime. Most services offer a presence information feature, indicating whether people on one's list of contacts are currently online and available to chat. This may be called a contact list.” Wikipedia:Instant messaging.
