What makes an ad worth spreading?

Today we bring you a guest post from Chris Anderson, Curator of TED, a nonprofit devoted to Ideas Worth Spreading from three worlds: Technology, Entertainment, Design. Anderson explains how TED and YouTube are teaming up to present a challenge called 'Ads Worth Spreading'.

Video is a powerful medium for spreading ideas. Over the past four years, TED has posted over 800 TEDTalks on TED.com and on YouTube. We've been thrilled to see the world respond -- watching the videos more than 375 million times.

Our mission -- of spreading ideas around the world -- is supported in part by advertising. And we believe that advertising should evoke the same emotions a TEDTalk does -- it should make you think, make you respond, make you want to share -- a great idea, a product that makes the world better, an initiative that might change the world. Like YouTube, we want to see the same level of passion in online ads as we do in our TEDTalks. So, we’ve created a challenge called 'Ads Worth Spreading' to solicit the best ads that raise the bar, elevate the craft and invent new forms of online engagement.

We invite you to enter the competition. Entries can be hysterically funny, stunningly beautiful, or just intriguing, fascinating, ingenious and persuasive. For inspiration, check out examples of great creative on YouTube Show and Tell. It is free to enter, the submission deadline is February 7, 2011, and full contest rules are right here.

We’re excited to see your ads worth spreading!
