The TED Interview is back for a special season. Chris Anderson, Head of TED, returns as host to investigate the ultimate idea worth spreading: Infectious Generosity. Inspired by Chris’s book of the same name, this season will explore how even small acts of kindness have the potential to spread and impact millions – and ultimately build a more hopeful future for all. Listen in as amazing people and great thinkers share how they aim to change lives at a scale never experienced before.

And in the spirit of infectious generosity, listeners can receive a free copy of Chris’s book in e-book or audio format. Just visit ted.com/generosity and fill out the short form to receive yours.
