From Wikipedia:

Udemy serves as a platform that allows instructors to build online courses on topics of their choosing. Using Udemy’s course development tools they can upload video, PowerPoint presentations, PDFs, audio, zip files, and live classes to create courses. Instructors can also engage and interact with users via online discussion boards. Courses are offered across a breadth of categories, including business and entrepreneurship, academics, the arts, health and fitness, language, music, and technology. Udemy also offers Udemy for Business, enabling businesses access to a targeted suite of over 1,000 training courses on topics from digital marketing tactics to office productivity, design, management, programming, and more. With Udemy for Business, organizations can also create custom learning portals for corporate training.

Some of my favorite instructors so far are (alphabetical order):
