Twenty-five years ago, the Massachusetts Institute of Technology made a bold move that most universities would never dare. Instead of locking its world-class course materials behind campus walls, MIT decided to put nearly its entire curriculum online, completely free for anyone with an internet connection. That decision gave birth to MIT OpenCourseWare (OCW). What began as a bold experiment in 2001 has become one of the most significant educational initiatives in history. Today, OCW provides materials from more than 2,500 undergraduate and graduate courses across virtually every discipline: physics, engineering, artificial intelligence, economics, biology, mathematics, computer science, and many more. Anyone can access lecture notes, problem sets, exams, syllabi, and a growing library of video lectures, with no tuition, no application, and no account required. According to MIT, more than 500 million people worldwide have used these resources over the past 25 years. The impact has been profound. Students use it to ace exams, explore new fields, and launch careers. Educators around the globe integrate the materials into their own teaching. Many learners credit OCW with helping them pass professional certifications and unlock new opportunities. Beyond its direct benefits, OpenCourseWare helped spark the global open education movement, inspiring dozens of other universities to share their knowledge freely online. Even more impressive: the project was originally planned as a 10-year initiative. A quarter-century later, it's still expanding. MIT now aims to reach 1 billion learners in the coming decade, while enhancing the experience with powerful new AI-powered learning tools.
