Bastante bueno, incluye algunos gráficos o cita estudios con la data a la que hace referencia. Te da unos STEPPS (Social Currency, Triggers, Emotions, Public, Practical Value, Stories) para medir los factores que según Berger predicen y/o explican la viralidad de una campaña. También incluye algún ejemplo importante sobre cómo aprovecharla para tu marketing; de nada sirve que algo sea viral y no te pague dividendos a ti directamente. Le pondría 5 y sí creo que es un must read pero no me gusta cómo escribe este tío.

The movie Inception blew my mind. This book had the exact same effect. First, this book made me realize the STEPPS (haha!) that I need to take if I ever want to his 1,000,000 views on Youtube (a current goal of mine--after that many views you make money). So not only is it useful in my personal life (it would also be very useful in advertising or marketing) but it helped me realize the way I act as an effect of what I encounter in my daily life.

For example: My roommates and I buy a lot of special edition Birthday Cake flavored Oreos. Yes, they're good. But why do I buy them literally ever single time I see them? Because they have Social Currency ("OMG have you tried the birthday Oreos? So delicious! They taste just like funfetti frosting!), several Triggers (dessert, food, Oreos, cookies, birthdays, special editions) and Stories (the thrill of the chase, because we literally tell everyone what store we last saw them at because we can never find them). Most importantly, I realized that part of the Social Currency category with birthday Oreos is that they're a special edition, and thus the last bag I bought could be the last bag I ever eat. I continue to buy them because I'm afraid I'll never be able to have them again. I don't usually buy other Oreos because, hey, they're always there.

This book is literally changing my life and opening my eyes to things that I had never before thought to think of. I was very, very impressed with this book. I cannot stress that enough.

Also, I feel like this book carries a lot of Social Currency, Triggers, Emotions, Public Visibility and Practical Value. I feel so hip to have read it and to be able to share it with all of my friends.

I received this book for free from the Goodreads First Reads program (and I'm thrilled about it!).

DNF.
I'm just not into this...

rating five stars not because this blew my mind with groundbreaking information but I feel that this is a good first read for anyone looking to venture into any field where they need ideas to be “contagious”

Interested in business, marketing, and advertising, I found 'Contagious' recommended across the Internet while searching for related books to study. Immediately checking it out of my local library, I delve into the book.

Since word of mouth is the most common media for conveying information, the question shifts to 'how to make people share (about a particular product/idea)'. Berger identified the keys for producing virality or boosting sales, called STEPPS.

Spoiler

1. Social Currency: People tend to share things that make them look good, not stupid. Therefore, remarkability, superiority, and exclusivity matter.
2. Triggers: Conversations are triggered by things people see, and a good example pointed out in the book is that KITKAT has successfully linked their chocolate bar with coffee so that whenever people see coffee, they are more likely to think about KITKATs.
3. Emotion: Things with higher physiological arousal level (awe, excitement, amusement; anger, anxiety) tends to get shared more, not necessarily those that induce positive emotions.
4. Public: Things must be visible for more people to see. In other words, 'make the private public'.
5. Practical Value: Usefulness is one of the reasons something gets shared.
6. Stories: In Berger's words, 'Information travels under the guise of what seems like idle chatter.'

With all the wide-ranging advertising examples and the 6 points of STEPPS Berger put together, I regard this book as an entertaining read indeed.

If you've read Gladwell's "The Tipping Point," then I suggest you read this also. This book digs a little deeper and presents concepts slightly differently. After most of the examples in this book, I found myself thinking, "oh wow...yeah!" So much put into marketing is so subtle. Epilogue provides a great content summary.

Muy ligero de leer y divertido, me gustan los libros que, mientras los lees, vas pensando cómo aplicarlo a tus negocios. No me gustó que siento que los conceptos básicos son buenos pero muy cortos, y al intentar hacer un libro más grande le puso un poco de paja, pero recomendable en general.

A book of common sense insights, written with hype and lots of lines like "I bet you didn't know...". This seems to be a very basic cliff notes of a egotistical professor's presentation to corporate sales reps.

I enjoyed this book. It was a tad slow, but the usage of anecdotal examples made it more interesting and relatable. I learned lots of new information, but what I found more valuable / helpful was the way the author put concepts I knew existed into proper terms.

What I liked:
The author uses examples that I found relatable and easy to understand. (Restaurants, cat videos, fantasy football)

The tone was serious but had a lightness to it that made it easy to read and smile whilst reading it.

I LOVED the variety of examples — it made the overall thesis / summary feel much more applicable than the examples that the author had chosen. It didn’t feel like the author specially picked examples to prove his point true, it felt like the author drew conclusions from the available data.


What I didn’t find quite so elite:
The book felt a tinge repetitive. I think that the author was trying to prove his point, but at times the book felt slow.
