TED podcasts
This is a world-famous non-profit organisation that began its work in 1984, and its mission is to spread innovative ideas (hence its motto, Ideas Worth Spreading). Currently, TED holds events and publishes the talks in podcast format, in addition to video format.
TED talks discuss global problems, business, science and many more exciting topics with a curious look and alternative solutions. You will find the most important ideas in each subject by listening to TED Talks Daily, TED Business and TED Kids and Family.
