One example that comes to mind is Kahn academy. They've built out new pedagogical methods.

There's also Unacademy a company I'm sure has helped millions of people learn new things.

Khan Academy uses lectures.

Very different types of lectures. Small chunks of info, lots of graphical representations, etc. These are very different that the type of lectures I had in school.

His lectures are terrible explanations and he doesn’t use professional looking graphics. Khan Academy is not a good product. My opinion refers solely to the math content.
