A list of the most popular MOOCs to consider in 2023

Massive open online courses help learners across the globe acquire new skills, brush up on their professional skills and pursue credentials. Explore some favorite platforms.

Education -- like every other sector -- underwent a digital transformation in the 2010s as the widespread availability of high-speed internet connections and cloud computing let educators offer online courses at scale.

Millions of learners over the years have taken such courses, and demand for access remains strong.
