Contagious

We?re all familiar with the idea of something?a video clip, for example?going viral. But how does it happen? Berger identifies six principles that operate, either singly or in combination, when anything goes viral, including social currency (a restaurant makes itself so hard to find that it becomes famous); emotion (the clip of Susan Boyle?s first appearance on Britain?s Got Talent exploded on YouTube because people reacted to it emotionally); triggers (more people search online for the song ?Friday? on Friday than on any other day of the week); and practical value (a man?s video showing how to cleanly shuck a cob of corn exploded due to its useful application). Some of what the author talks about here will seem utterly obvious, but there is plenty of insider stuff as well (for example, the brain trust at Apple debated which way the logo should face on the cover of its laptops: rightside up to the user, or rightside up to someone looking at the laptop?s open lid?). On such decisions are fortunes made. An engaging and often surprising book. *This book may have remainder mark
