Ted Talks present bold ideas from the world's leading thinkers. There's only one problem: They can be too long.
The attention span for most YouTube viewers sits around two or three minutes, and Ted Talks often clock in closer to 20.
That's where The Big Think comes in.
Take the conceptual grandeur of Ted Talks, replace the studio audience with a simple white background, shrink the presentation down to a more easily consumable size and you have The Big Think.
It's not that The Big Think dodges in-depth presentations. Its YouTube channel has plenty of videos that approach the hour mark.
But its backbone is comprised of hundreds of regularly uploaded shorter pieces from interviews with thinkers, entertainers and policymakers on everything from how we perceive color to how World of Warcraft could revive the economy.
And it's a star-studded cast. "Science-Guy" Bill Nye recorded one on why creationism isn't appropriate for children. Howard Dean argued why America should go over the fiscal cliff. Penn Jillette, Malcolm Gladwell and Henry Rollins have also made videos.
But if you want to learn why the penis is shaped like it is from Scientific American's Jesse Bering, you'll have to sit still for a full 14 minutes.
