Online education actually began before computers were even a thought. Long distance learning originated in the 1700s, and then the International Correspondence School came about in the late 1800s. Radio courses came about in the 1920s, followed by televised courses about 30 years later. The first networked computer teaching system happened in 1960. In 2009, over 5.5 million students were enrolled in online courses. It is expected that online education enrollment will continue to grow.
