History of Distance Learning
The first initiative in the field of distance learning was the announcement of Boston Newspaper for shorthand lectures in 1728 in the United States of America. The first practice was Sir Isaac Pitman’s shorthand teaching by letter in 1840 in England. The University of London started offering distance learning degrees in 1858 and became the first university in this area. 
Distance learning, which first started with letters, was supported by telegraph, telephone, radio and film strips in the mid-1980s and early 1900s, and in parallel with the rapid developments in television and later video and computer communication systems technologies, its dimensions have expanded today considerably.
With the digital transformation, distance learning is widely applied today in the form of electronic-learning (e-learning), both formally and informally.
