Distance learning can expand access to education and training for both general populace and businesses since its flexible scheduling structure lessens the effects of the many time-constraints imposed by personal responsibilities and commitments. The widespread use of computers and the internet have made distance learning easier and faster, and today virtual universities deliver full curricula online. The capacity of Internet to support voice, video, text, and immersion teaching methods made earlier distinct forms of telephone, videoconferencing, radio, television, and text-based education somewhat redundant. However, many of the techniques developed and lessons learned with earlier media are used in Internet delivery.
