Educational technology has in Colombia a recent history, and its importance is known only to limited circles; therefore this phenomenon has not been understood nor studied by large areas of the national opinion. The public is completely ignorant in this field and the government encourages this situation. The 1st step was made in 1948 by a priest who used the radio as a tool for the education of the citizens. This project faced several technical and scientific obstacles, such as the large volume of the radios, the rarity of electricity in rural areas, the cost of receiving sets and the lack of a technical service. However, the project developed; its actual name is ACPO and its broadcasting station is Radio Sutatenza. ACPO's main function is to provide the rural areas of Colombia with "education and culture"; to do this, ACPO has powerful resources such as: a broadcasting network which covers the whole country plus some neighbouring countries; one of South America's most modern presses; and powerful economic means. From its creation to this day, the education of the Colombian peasant has been the monopoly of ACPO. Television appeared in Colombia in 1954. It was imported with the prospect of using it in the field of education. Television is in the hands of the Organization of American States, which created multinational centres. The system is controlled from Florida, where the staff is trained. In 1969 the international audio-visual centre (Cavisat project) was created, whose base is in Colombia; its goal, a world-wide policy of education available to everyone. The strategy of the Colombian government is to open up education to any type of research, thus preparing the ground for the new imperialistic strategy: to create conditions in which educational technology becomes a need so that its level of development and the logic with which the system was conceived impose with their own strength the general decisions which become necessary in order to transform it into an official model for Colombian education.
