– After several years of TED lectures there is a fantastic inventory of 1204 lectures which is made available here.

– The global classroom of the Khan Academy is reaching currently more than 3200 video’s with lessons and exercises.

– The Udacity university with professors from Stanford  is also expanding in open courses integrating didactic sets of learning resources.

– Academic Earth is steadily growing in its offer and is combing lectures from different top universities

– The University of the People is the last one in line we want to mention with the objective to democratize education.
