In 2010 worldwide instant messaging accounts will total 2.3 billion and will grow to 3.4 billion by 2014, according to the latest study by The Radicati Group Inc.
Increasingly IM services go beyond simple text-based messaging and offer other features such as voice chat, video chat, social network connectivity and support for mobile devices.
IM is defined as real-time text messaging transmitted through a network between two or more users. The IM market is comprised of products or services that either facilitate IM conversations or secure and manage its usage.
The study divides the market into four segments: Public IM, Enterprise IM, IM Management and Security and IM Aggregators.
