Udemy was founded in 2009 in San Francisco by Eren Bali, Gagan Biyani and Oktay Caglar. In time Udemy became a large global platform for online teaching and learning. Udemy is both for laerners and teachers, offering free and paid videos. In a sense Udemy has become identical with online video learning. One other characteristic -and perhaps disputable- feature of Udemy is that it conducts huge discounts very often. Great for the learners, but not so great for the teachers!
