TED: The mission is spreading ideas

TED is a global community, welcoming people from every discipline and culture who seek a deeper understanding of the world. We believe passionately in the power of ideas to change attitudes, lives and, ultimately, the world. On TED.com, we're building a clearinghouse of free knowledge from the world's most inspired thinkers — and a community of curious souls to engage with ideas and each other, both online and at TED and TEDx events around the world, all year long

TED is a nonprofit devoted to spreading ideas, usually in the form of short, powerful talks (18 minutes or less). TED began in 1984 as a conference, where Technology, Entertainment and Design converged, and today covers almost all topics — from science to business to global issues — in more than 100 languages. Meanwhile, independently run TEDx events help share ideas in communities around the world.

Royal Society for the Encouragement of Arts

The RSA is a non-profit organisation working to meet 21st century challenges by showcasing ideas, undertaking innovative research and building civic capacity around the world.

We believe that all human beings have creative capacities that, when understood and supported, can be mobilised to deliver a 21st century enlightenment. We work to bring about the conditions for this change, not just amongst our diverse Fellowship, but also in institutions and communities. By sharing powerful ideas and carrying out cutting-edge research, we build networks and opportunities for people to collaborate - creating fulfilling lives and a flourishing society.

Brain Pickings

The core ethos behind Brain Pickings is that creativity is a combinatorial force: it’s our ability to tap into our mental pool of resources — knowledge, insight, information, inspiration, and all the fragments populating our minds — that we’ve accumulated over the years just by being present and alive and awake to the world, and to combine them in extraordinary new ways. In order for us to truly create and contribute to the world, we have to be able to connect countless dots, to cross-pollinate ideas from a wealth of disciplines, to combine and recombine these pieces and build new ideas.
