I came across a post by Adam L. Penenberg, author of the Viral Loop, in which he talks about entrepreneurs who built multimillion- and billion-dollar businesses from scratch by ‘building virality’ into their products and services. He says:
“At some point, as the number of users doubles, then triples, the company achieves what’s known as a “viral loop,” when the product spreads even if the company does nothing to promote it. The trick is that they all created something people really want, so much so that their customers happily spread the word about their product for them. The result: Never before has there been the potential to create wealth this fast, on this scale, and starting with so little.
It’s interesting to think of Internet businesses, such as Facebook and Twitter, that have been built around this viral model — “to use the product, you have a strong incentive to spread it”.
