With the introduction of the World Wide Web in 1989, the advances in technology have gotten more people online and has led to a boom in online education.
Nowadays, we see many universities offering more distance learning options, which has certainly evolved over the years. Historically, some colleges offered courses through radio broadcast to a newer method by distributing educational materials on CDs.
The more popular way to access educational courses are MOOCs (Massive Open online Courses), which are free courses offered by colleges and they are open to anyone who wants to take a class. These type of courses have been made popular by start-ups such as edX.org, Udemy, Udacity and Coursera.
