The New York Times bestseller that explains why certain products and ideas become popular.

“Jonah Berger knows more about what makes information ‘go viral’ than anyone in the world.” —Daniel Gilbert, author of the bestseller Stumbling on Happiness

What makes things popular? If you said advertising, think again. People don’t listen to advertisements, they listen to their peers. But why do people talk about certain products and ideas more than others? Why are some stories and rumors more infectious? And what makes online content go viral?

Wharton marketing professor Jonah Berger has spent the last decade answering these questions. He’s studied why
New York Times articles make the paper’s own Most E-mailed list, why products get word of mouth, and how social influence shapes everything from the cars we buy to the clothes we wear to the names we give our children.

In
Contagious, Berger reveals the secret science behind word-of-mouth and social transmission. Discover how six basic principles drive all sorts of things to become contagious, from consumer products and policy initiatives to workplace rumors and YouTube videos. Learn how a luxury steakhouse found popularity through the lowly cheesesteak, why anti-drug commercials might have actually increased drug use, and why more than 200 million consumers shared a video about one of the most boring products there is: a blender.

Contagious provides specific, actionable techniques for helping information spread—for designing messages, advertisements, and content that people will share. Whether you’re a manager at a big company, a small business owner trying to boost awareness, a politician running for office, or a health official trying to get the word out, Contagious will show you how to make your product or idea catch on.

Editorial Reviews

Review

“Jonah Berger is as creative and thoughtful as he is spunky and playful. Looking at his research, much like studying a masterpiece in a museum, provides the observer with new insights about life and also makes one aware of the creator's ingenuity and creativity. It is hard to come up with a better example of using social science to illuminate the ordinary and extraordinary in our daily lives.” -- Dan Ariely, James B. Duke professor of psychology and behavioral economics at Duke University and bestselling author of Predictably Irrational

“If you are seeking a bigger impact, especially with a smaller budget, you need this book.
Contagious will show you how to make your product spread like crazy.” -- Chip Heath, co-author of Made to Stick and Decisive

“Why do some ideas seemingly spread overnight, while others disappear? How can some products become ubiquitous, while others never gain traction? Jonah Berger knows the answers, and, with
Contagious, now we do, too." -- Charles Duhigg, author of the bestselling The Power of Habit

“Jonah Berger knows more about what makes information ‘go viral’ than anyone in the world.” -- Daniel Gilbert, Professor of Psychology, Harvard University and author of Stumbling on Happiness

“Jonah Berger is the rare sort who has studied the facts, parsed it from the fiction—and performed groundbreaking experiments that have changed the way the experts think. If there’s one book you’re going to read this year on how ideas spread, it’s this one.” -- Dave Balter, CEO of BzzAgent and Co-founder of the Word of Mouth Marketing Association

“Think of it as the practical companion to Malcolm Gladwell’s
The Tipping Point.” -- Tasha Eichenseher ― Discover

“[Berger] sheds new light on phenomena that may seem familiar, showing with precision why things catch on. . . . As a playbook for marketers,
Contagious is a success.” -- Danielle Sacks ― Fast Company

“Contagious contains arresting — and counterintuitive — facts and insights. . . . Most interesting of all are the examples Berger cites of successful and unsuccessful marketing campaigns.” -- Glenn C. Altschuler ― The Boston Globe

"For nonexperts who puzzle about the best way to make an impact in a world of social media addicts with short attention spans, it provides plenty to think about. . . . If there were a 'like' button underneath it, you'd probably find yourself clicking it." -- Maija Palmer ―
Los Angeles Times

“An infectious treatise on viral marketing. . . . Berger writes in a sprightly, charming style that deftly delineates the intersection of cognitive psychology and social behavior with an eye toward helping businesspeople and others spread their messages. The result is a useful and entertaining primer that diagnoses countless baffling pop culture epidemics.” ―
Publishers Weekly

“The book is just plain interesting. Berger’s cases are not only topical and relevant, but his principles seem practical and are easily understood. . . . I have a strong feeling that this book will catch on.” -- Ben Frederick ―
The Christian Science Monitor

"An exegesis on how ideas really 'go viral' (hint: the internet gets too much credit) by a marketing wunderkind." ―
Details

"A provocative shift in focus from the technology of online transmission to the human element and a bold claim to explain 'how word of mouth and social influence work . . . [to] make any product or idea contagious." ―
Kirkus Reviews

Absolutely incredible. One of the best books I've ever read
After reading Contagious, I felt the need to buy Invisible Influence and The Catalyst. I love Jonah Bergers writing style. Very easy read. Each topic is broken down by chapters and each chapter is full of real world studies and examples. I have recommended all three of these books to many people now. Whether you work in advertising/marketing, own a business, or just have a genuine interest in the human psyche...these books are absolutely worth owning. Stop reading my review already and buy it. As a matter of fact, order multiples, so you can give some away. After I read them I immediately went back and bought more so I can keep copies to give to people. That's how good they are.
Thank you for your feedback

Reviewed in the United States on October 11, 2020
New york time’s best seller, “Contagious: why things catch on”, by Jonah Berger, goes through many examples of the methods used to catch the attention of the majority of people, and what gets ignored. Berger says “regardless of how plain or boring a product or idea may seem, there are ways to make it contagious…”. The author presents real life examples to illustrate points in order to inform the reader on why things catch on, in a marketing perspective. Berger has studied why things go “viral” and claims that most communications of products are not through the internet, but by word-of-mouth. This book is useful when learning about why some businesses fail and others have booming businesses. It is split up by the acronym STEPPS- Social currency, Triggers, Emotion, Public, Practical value, and Stories, with examples of real businesses in each, which is also useful.
Traditional marketing suggests that the factors that determine a business’ or product’s success are quality, price, and the advertising. Berger explains that it is much deeper than that, and that the more important factors are word-of-mouth transmission and social influence. Word-of-mouth is much more effective because it is persuasive, because people trust more what others recommend rather than what they see on T.V. or social media. This was very interesting to read and I agree with his points- and the numbers prove it accounts for 20-50% of all purchasing decisions. Shockingly, only 7% of word-of-mouth advertising is done through social media.
The author's main arguments are split up by the STEPPS acronym, and each is successfully argued with facts and experience. The first chapter starts with Social currency. This chapter puts emphasis on being “in the know” on something, and wanting to share it with others. The example Berger used was the hot dog restaurant having a secret bar hidden with a secret door in a phone booth. The restaurant and bar have done well for years because people feel like they are “in the know” and recommend it to others, as if they are a part of some big secret. The next chapter, Triggers, is about how one thing triggers another. Such as buying coffee and donuts, peanut butter and jelly, and specifically in the book it is mentioned that the Mars candy company saw a spike in sales during the time in 1997 when NASA was organizing a mission to Mars. Emotion is all about how when something provokes emotion or inspires you, you are more likely to share it. Public is about how people imitate others, with the example of how people are more likely to choose a restaurant or store that has more people in it, and to walk past the ones that are empty. Next, practical value is about how important information is more useful to share, and relies heavily on buyer behavior because people like to help others . Finally, stories explains how a good story is likely to be told especially when it provokes emotion, and thus makes people want to share it with others.
In my opinion, “Contagious: why things catch on” by Jonah Berger is a very interesting read with useful information. As soon as you pick up the book it is difficult to put it down, as it keeps the audience engaged and interested. It is very easy to understand and it allows the reader to put into perspective that marketing is deeper than just advertising on social media. This book could be particularly very useful to students who are interested in studying marketing, interested in psychology and why people are influenced by certain things and not others, or people who have plans to start a business- or just anyone on social media. “Contagious” could even be useful to people who simply do not want to be manipulated by businesses and gain the ability to see through the different marketing strategies. Not only are you given real life scenarios and statistics, but also you are shown proof on how STEPPS can help create a booming business. The stories that are provided are especially useful as they keep the reader engaged while also providing useful information. The only negative of this book I found was the way it is written, as it repeats a lot and could be interpreted as reading a children’s book, and some may get a bit bored. Readers may want to skip over parts as it repeats the same ideas during the chapter and may find it to be a bit redundant at times.
Overall the information is useful enough that I did not mind it too much as I found it just makes it a quick read on why things go viral and how businesses manipulate customers. I enjoyed reading this book, and if you plan on developing a marketing plan or strategy for your business, “Contagious: why things catch on” would be useful to test the strategies to make sure it would be successful. The author successfully explains the STEPPS to making a business successful and used his own education and research to back up the claims being made. The book did not really come off as persuasive, just informative of what works and what does not. I definitely recommend this book to anyone who wants to know more about how marketing strategies work and how companies can manipulate you.
Similar books to “Contagious” include: "Diffusion of Innovations," by Everett Rogers, “Influence” by Robert B. Cialdini, and “The Nuclear Effect” by Scott Oldford. Jonah Berger also has other books that talk about marketing and how to influence other people, such as “The Catalyst” and “Invisible Influence”. Overall, “Contagious” by Jonah Berger is an excellent book to start off with if you want to understand the aspects of marketing and advertising and what can make a company successful, especially when today it is harder than ever to find what will stick to consumers, this book brings about the most effective and prosperous ways on making your product or business contagious.

Reviewed in the United States on June 26, 2013
What if you had the secret sauce that could make your next campaign go viral? What if you knew the secret to making your content get shared across the internet? What if six basic principles explained everything from Rebecca Black to the power of $100 cheesesteaks?

Wharton Professor Jonah Berger makes some bold claims in his latest book Contagious: Why Things Catch On. But like Malcolm Gladwell and the Heath brothers before him he backs up those claims with enlightening data and cohesive story telling.

WHAT I LOVED ABOUT THE BOOK:

1. Berger makes clear early on in Contagious that "...Facebook and Twitter are technologies, not strategies". This isn't a book based on building followers or getting likes. This is a book with clear, practical and ingenious steps that can make most anything contagious...even blenders.

2. Berger provides an easy way to remember his principles, which means they will stick with the reader long after they have put this book down. They are the "Six Key STEPPS".

Social Currency - we share things that make us look good

Triggers - top of mind, tip of tongue

Emotion - when we care, we share

Public - built to show, built to grow

Practical Value - news you can use

Stories - information travels under the guise of idle chatter

3. Most of the ideas that Berger discusses have two great qualities.

One is the sense that you as the reader could have thought of that. None of the social epidemics Berger highlights seem beyond the creative capacity of you or me.

Two - we can do these things! We can take what Berger has written about so eloquently and use these ideas in our lives and businesses to our benefit.

That is what any great book should do and Berger has written that book.

WHAT I DIDN'T CARE FOR ABOUT THE BOOK:

I can honestly say this is one of the best books I've read in 2013. Berger is to the point, every page offers valuable tips and tactics and when an author is not only intelligent but a great storyteller all you can say is thank you and please write another.

CONCLUSION:

If you are in the business of products, ideas or behaviors and you have a vested interested in making that business ignite social epidemics this is the book that can act as the match to start that fire. I highly recommend this book.

This book is all based on his academic research about 𝐰𝐡𝐚𝐭 𝐠𝐞𝐭𝐬 𝐭𝐡𝐢𝐧𝐠s 𝐬𝐡𝐚𝐫𝐞𝐝; or, in other words, “word of mouth” . 

Why is word-of-mouth a topic worth a book?
Because it's the primary factor behind 20% to 50% percent of all purchasing decisions and it’s more targeted and persuasive than traditional advertising. 

Berger talks about 𝟓 𝐩𝐫𝐢𝐧𝐜𝐢𝐩𝐥𝐞𝐬 that, according to his research, activate word of mouth:
- Social currency: We share things that make us look good.
- Triggers: Top of mind, tip of tongue.
- Emotions: When we care, we share.
- Public: Built to show, built to grow.
- Practical value: News you can use.
- Stories: Information travels under the guise of idle chatter. 

Nowadays we all spend more and more time online. 
One thing got my attention in this book:
“Only 7% of word of mouth happens on-line. Offline word of mouth is much more important”.

That's good news....
