Here is an interesting potted history of virtual learning environments on Wikipedia
A virtual learning environment (VLE) is a system that creates an environment designed to facilitate teachers in the management of educational courses for their students, especially a system using computer hardware and software, which involves distance learning.
Virtual learning environments are often referred to as "learning management system" (LMS) or Managed Learning Environment (MLE) or Online Learning Environment (OLE).
