Long before anyone had heard of a learning management system, online classroom, or even a university campus, people were finding creative ways to learn across distances. The story of open and distance learning (ODL) stretches back nearly two centuries – from handwritten postcards sent through the mail to AI-powered platforms delivering courses to millions worldwide. Understanding how ODL evolved helps us appreciate not just where education has come from, but why its core mission – making knowledge accessible to everyone – has never changed.

Phase one: the birth of correspondence education
The roots of distance education trace back to 1728, when Caleb Phillips placed an advertisement in the Boston Gazette, offering to teach shorthand to anyone willing to receive weekly lessons by mail. It was a modest beginning, but it planted a seed. The concept remained largely experimental until 1840, when Sir Isaac Pitman formalised it into something far more structured.
Pitman began teaching his shorthand system by mailing transcribed texts on postcards to students, who would complete the exercises and send them back for correction. The introduction of uniform postage rates across England in 1840 – the “Penny Post” – made this scheme both affordable and scalable. Crucially, Pitman’s method included genuine feedback: he not only received student work but corrected it and returned it with comments. This two-way exchange was what separated his system from earlier one-way broadcasts of knowledge.
The model spread quickly. The University of London became the first university to offer distance learning degrees through its External Programme, chartered in 1858, which Charles Dickens famously called the “People’s University” for opening higher education to less affluent students. In the United States, the International Correspondence Schools (ICS) were founded in 1888 to help immigrant coal miners pass safety exams, and by 1906 had accumulated nearly 900,000 enrolled students. By the 1890s, major universities including the University of Chicago and the University of Wisconsin had launched full correspondence departments, making college-level study available to workers, rural residents, and anyone who could not attend in person.
What made correspondence education significant
Correspondence education was not simply a workaround for people who couldn’t reach a campus. It was a deliberate democratisation of knowledge. It opened doors for women, working-class people, and rural learners who had previously been shut out of formal education entirely. The benefits were straightforward: flexibility, affordability, and access. Students set their own pace, studied in their own space, and earned real qualifications. These principles – which today seem obvious – were genuinely radical in the 19th century.
Phase two: the open education movement
By the mid-20th century, correspondence education had proven its value, but it was still largely limited to printed materials sent through the post. The 1960s brought a new wave of thinking: what if education could be truly open – open not just in delivery, but in admissions, in philosophy, and in ambition?
The most significant institution to emerge from this era was the UK Open University (OU). Founded in 1969 under the Labour government of Harold Wilson, the OU was built on Michael Young’s vision of a “teleuniversity” that could use telecommunications to reach a far wider and more varied student population than traditional institutions. Planning had begun in 1965, led by Minister of State for Education Jennie Lee, who assembled a committee of university vice-chancellors, educationalists, and broadcasters to design something genuinely new.
The OU adopted a radical open admissions policy that took into account work and life experience, not just academic qualifications. When it accepted its first 25,000 students in January 1971, other UK universities were opening with only a few hundred. By 1987-1988, yearly enrolment had doubled to 100,000 students, and reached 200,000 by 2001-2002. Today, more than 2.3 million students have studied with the Open University, making it the largest academic institution in the United Kingdom by student numbers.
The role of media and support systems
What made open universities genuinely different from earlier correspondence models was the sophisticated mix of learning tools they employed. The OU began with correspondence-style study packs of textbooks and study guides, supplemented by audio tapes, video tapes, and television lectures broadcast through the BBC. It was one of the first universities to systematically use television and radio broadcasts for educational purposes, a model that would influence institutions worldwide.
Equally important were the learner support structures built around these materials. Tutors were distributed across regional centres; summer schools provided face-to-face interaction; and a credit transfer system allowed students to build qualifications incrementally. The OU also pioneered education for prisoners and disabled students, embedding social justice at the heart of its mission. The open university model proved so successful that similar institutions sprang up across the world – from Indira Gandhi National Open University (IGNOU) in India to the Open University of Sri Lanka and beyond – each adapting the principle of widening access through distance and media-based learning.
Phase three: virtual education and the internet era
The third and current phase of ODL began taking shape in the 1990s, when the World Wide Web transformed how people accessed information. This was not just a change in delivery mechanism – it was a fundamental shift in what education could look like.
The 1990s marked a significant turning point, with the widespread availability of the internet giving rise to web-based courses accessible to a global audience. Learning Management Systems (LMS) like Blackboard emerged in this period, providing structured digital platforms for online courses. Universities and colleges began experimenting with online courses in the early to mid-1990s, but rapid growth in mainstream institutions only accelerated from 1998 onward, when institutions like New York University launched dedicated online education subsidiaries.
From online courses to a global learning ecosystem
The 2000s saw online learning move from the experimental fringes to the educational mainstream. High-speed internet made multimedia content seamless to deliver, and virtual learning environments provided more engaging, interactive experiences. In 2001, MIT launched OpenCourseWare, making its course materials freely available and sparking a global open educational resources movement. Then in 2012, platforms like Coursera, edX, and Udacity launched Massive Open Online Courses (MOOCs), making high-quality instruction from top universities available to anyone with an internet connection.
The COVID-19 pandemic in 2020 acted as a sudden, worldwide stress test for virtual education. Schools and universities around the world were forced to pivot to remote instruction overnight, highlighting the resilience and adaptability of online learning. What had once been considered an alternative model became, for a period, the only model. It accelerated adoption that might otherwise have taken another decade.
Learner-centred design and the new pedagogy
The defining characteristic of virtual education is not the technology itself – it is the pedagogical shift toward learner-centredness. Unlike the one-way transmission model of early correspondence courses, virtual education enables asynchronous and synchronous interaction, peer collaboration, self-paced progression, and personalised learning pathways. The integration of audio, video, 3D content, and blended learning models has made online education a full-scaled method of knowledge delivery rather than a simplified substitute for the classroom. AI-powered tutoring, adaptive assessments, and predictive analytics are now further reshaping how instruction is individualised at scale.
Today’s virtual education environment is also defined by its breadth of access. From undergraduate and graduate degrees to professional development and micro-credentials, platforms like Udemy, Coursera, and edX serve learners across virtually every subject and skill level. For the first time in history, a student in a rural town, a working parent, or someone in a developing nation can access the same course content as a student on a campus in London or Boston.
A thread running through three centuries
What is striking about this evolution is the consistency of purpose across all three phases. Whether it was Isaac Pitman correcting shorthand exercises on postcards, the Open University broadcasting lectures at midnight for shift workers, or Coursera streaming a machine learning course to a student in Lagos, the goal has remained the same: to bring quality education to those who would otherwise be excluded. Each technological shift – from the postal system to broadcasting to the internet – has been adopted not for its own sake, but because it extended the reach of that mission.
The phases did not simply replace one another either. Correspondence principles still underpin much of how distance education is designed. Open university models of learner support, media integration, and flexible admissions continue to shape how online institutions operate. Virtual education built directly on the infrastructure – physical, institutional, and philosophical – that came before it.
What do you think? As virtual education continues to evolve with AI and immersive technologies, do you think it can fully replicate the social and intellectual experience of a traditional campus? And looking back at the three phases of ODL, which shift – correspondence, open universities, or virtual learning – do you think had the most lasting impact on how we define access to education today?
