HISTORY:

The need for ITIL was emerged in 1980s when the British Government realized that they are far behind in the field of IT & the present quality of service is not meeting their demands. Ultimately the UK government gave this task to Central Computer & Telecommunications Agency (CCTA) .They was tasked to provide more efficient & reasonable use of IT resources.

The earliest version of ITIL was called Government Information Technology Infrastructure Management (GITIM).

During the early 1990s many large companies & Government agencies started adopting this framework. As the time passed it gained popularity & both Government & non government organizations started using it. Consequently it encompassed the whole world.
