A list of the most popular MOOCs to consider in 2026
Massive open online courses help learners across the globe acquire new skills and pursue credentials. Explore some of the best MOOC platforms available today.
Education -- like every other sector -- underwent a digital transformation in the 2010s as the widespread availability of high-speed internet connections and cloud computing enabled educators to offer online courses at scale.
Individual educators, educational institutions, government agencies and nonprofit as well as for-profit companies seized on that opportunity, creating massive open online courses (MOOCs) that are open to all interested learners. Over the years, millions of e-learners have taken such courses, and demand for access remains strong.
Reasons to consider MOOCs
MOOCs offer many advantages, particularly for professionals who want to add skills but don't have the time, money or incentive to pursue advanced degrees. According to experts -- including researchers, workplace trainers, education advocates and HR professionals -- the benefits of MOOCs include the following:
- Flexibility. Learners can access courses from anywhere and often at any time.
- Personalized and customizable learning paths. Learners can pursue topics that interest them to fulfill their unique knowledge gaps.
- Access to high-quality instruction. Many MOOCs have been created by highly selective academic institutions, large corporations, industry leaders and notable experts from a range of disciplines.
- Affordability. A high number of MOOCs are free, while fee-based options are generally available at a low cost.
- Inclusiveness. MOOCs are typically open to anyone interested in learning.
- Diversity of subjects. MOOCs span a range of academic and professional topics, allowing learners to pursue the areas that interest them the most.
