The origins of the LOI lie within the city's "Institute of Trade Sciences". In 1923 this institute started doing their first (postal) distance-learning programme: a course in book-keeping. Ove the years the the institute has started running several other courses and in 1941 (So, surprisingly, in war time) the institute teamed up with a number of Leiden-based colleges to run distant-learning courses on their behalf, all under the LOI-banner.
In 1953 the LOI started providing audio-based language courses (on good old fashioned casettes) and in 1988 the LOI started experimenting with something called "digimail", a computer-based form of distance-learning, the technology of which seemed to be quite similar to what we would later become familiar with under the name E-mail. In 1996 the LOI introduced what they called the "LOI campus", an online, web-based learning environment. Originally the campus provided only written lectures, later video-lectures (some also streamed live) and downloadable audio-lectures became available. Since 2001 most of the courses are almost completely web-based with lectures ebing given through audio, video and text, seminars taking place in forums and online audio/video conferences and most assessments being submitted online. The LOI provides students with their own personal tutor (or I-coahc, as they like to call them) with whom they keep in contact through both email as well as instant messenging.
In 2002 the LOI started doing a small number of full university degrees, completely through distance learning, which up until then these were only provided by the Open Universiteit (Obviously the Dutch equivalent of the Open Univerity). The two however are not really in competition though, as these two distant-learning giants provide different degree courses. The reason for this is probably because the LOI would find it hard to compete with the lower tuition fees of the government funded Open Universiteit. Nonetheless, the LOI-brand has pretty much become synonym with distance-learning in the Netherlands and some of the open university's online services are clearly inspired by the LOI's online campus.
