By now we're all pretty familiar with TED Talks and the TEDx Program. TED, a non-profit organisation began back in 1984 as a conference where tech, entertainment and design merged.
Today it covers almost every topic in popular culture from science to business to global issues in 18 minute speeches.
TEDx are independently run events that help share ideas in communities across the globe. There have been an incredible 1,800 TED Talks that have been watched more than 2.5 billion times.
And here are 15 of the must-see TED Talks from the past decade to entertain, educate and inspire you.
1. Edward Snowden- Here's How We Take Back The Internet

7. Jamie Oliver's TED Prize Wish- Teach Every Child About Food
Jamie Oliver is transforming the way we feed ourselves, and our children. Jamie Oliver has been drawn to the kitchen since he was a child working in his father's pub-restaurant. He showed not only a precocious culinary talent but also a passion for creating (and talking about) fresh, honest, delicious food. In the past decade, the shaggy-haired "Naked Chef" of late-'90s BBC2 has built a worldwide media conglomerate of TV shows, books, cookware and magazines, all based on a formula of simple, unpretentious food that invites everyone to get busy in the kitchen. And as much as his cooking is generous, so is his business model- his Fifteen Foundation, for instance, trains young chefs from challenged backgrounds to run four of his restaurants.
Now, Oliver is uses his fame and charm to bring attention to the changes that Brits and Americans need to make in their lifestyles and diet. Campaigns such as Jamie's School Dinner, Ministry of Food and Food Revolution USA combine Oliver's culinary tools, cookbooks and television, with serious activism and community organising to create change on both the individual and governmental level.
