Distance learning is a teaching method that instructs and delivers learning material to students via remote correspondence.  Throughout the course of human history, education was first a social privilege of the wealthy and elite.  As time progressed education rights were extended to citizens of developing nations.

However, pursuit of higher education posed obstacles for students physically unable to attend class.  With the advent of mail correspondence and development of the world wide web, distance learning has spurred realistic, scholastic opportunities for the public.
