The US Military has always striven to enhance training with technology, and pioneered e-learning when the Army Signal School stared to experiment with using television for training in the 1950s, and when the Air Force Institute of Technology began using commercial phone networks to deliver instructional content in the 1970s. In 1996, the Army created a distance learning program for troops to access college degree programs over a combination of Internet and satellite teleconferencing. Recently, the US military has been embracing the training potential of collaborative and mobile learning.
