If we have a look on the early forms of distance then we found that distance education had its beginning in the mid 1800s and then it took the form of

Correspondence

Postal system to facilitate the exchange of information

Then in 1920s the birth of the telecommunication industry provided the element that would most dramatically alter Distance learning to real time communications. First in 1920s came the capability of voice transmission and audio conferencing .Then video transmission allowed students to observe the classroom activities. Then emphasis is only on Radio and Television till 1970s.

By 1970s the world had begun to focus on the power of computer and then distance learning entered the virtual age. Now the internet has revolutionized the practice of providing class and degree programs to offsite students.
