Ideas change everything

Ideas change

Powerful ideas, powerfully presented, move us: to feel something, to think differently, to take action.

In a world that can feel dark and overwhelming, TED finds inspiring perspectives in every region, and shares them for free with an open, curious, global audience. These fascinating, often surprising ideas not only deepen understanding and spark new conversations — they drive meaningful change and build hope.

In 2023, TED discovered, staged and amplified 17,330 big ideas in the form of talks, animations, and podcasts.

Together, these ideas were heard more than 3 billion times, all around the world.

These ideas had ripple effects of many magnitudes, pointing toward the possibility of a better future for people, communities and humanity at large.
