IM (Instant Messaging)

A service that alerts users when friends or colleagues are on line and allows them to communicate with each other in real time through private online chat areas. While instant messaging has primarily been a proprietary service offered by Internet service providers such as AOL and MSN, businesses are starting to employ instant messaging to increase employee efficiency and make expertise more readily available to employees.
