Have you ever seen a TED talk video online? It was founded back in 1984.
Yes, I find them really informative. Do you like them?
Yes, and I agree. They address a wide range of topics within the research and practice of science and culture, often through story telling.
I see, I watched one recently about crime in north America. It was really interesting 
If you liked it I imagine you can learn about that topic in other regions.  TED events are also held in Europe and Asia.
Their events are really popular in those regions. I think many people find them engaging.
TED's slogan of "ideas worth spreading" really is so accurate.  TED originally was based on Technology and Design but has greatly broadened.
Thats great I think thats why it captures the imagination of many people.
