Moreover, the fairly recent popularity of TED Talks (Technology, Entertainment, Design) has been extraordinary. The totally diverse topics of TED Talks range from the personal to the political, from medicine and science, to religion and philosophy and much more. Billed as "funny," "beautiful," "fascinating," "informative," "courageous" and "inspiring," TED Talks are presented by well known figures such as Bill Gates, Al Gore, and Sheryl Sandberg as well as "nerds" one has barely heard of. Merely click on TED and no fewer than 1,700 current presentation topics appear. One could see them live or view them online.
