Book Review: How “Like” Became the Button That Changed the World – Insights from Martin Reeves & Bob Goodson
Have you ever wondered how a simple thumbs-up became the universal symbol of approval online—a tiny gesture that now shapes billions of interactions daily? If you’ve ever paused before tapping “like” on a post, you’re not alone. This unassuming icon, popularized on social platforms, has become so woven into our digital lives that we rarely stop to question its origin or power. But as Martin Reeves and Bob Goodson reveal in their eye-opening book, Like: The Button That Changed the World, the story behind the like button is as fascinating as it is consequential.
Let’s dive into why this book is a must-read for thinkers, innovators, and anyone curious about the invisible forces shaping human connection—and how a single button quietly rewired our world.
Why the Like Button Matters More Than You Think
We tend to take technology for granted, especially when it’s seamless and universal. The like button is the ultimate example. On the surface, it’s just a playful tap, a moment’s acknowledgment. But dig deeper, and you’ll find a portal into how humans crave validation, how businesses harness attention, and how culture itself can be subtly transformed by design.
Over 160 billion likes are tapped every day. That’s not just a stat—it’s a seismic shift in how we communicate approval, belonging, and emotion online. Reeves and Goodson—one a strategy guru, the other a Silicon Valley pioneer who helped invent the button—take us behind the scenes of this small but mighty feature.
The Origin Story: From Thumbs-Up to Global Icon
Tracing the Humble Beginnings
Before the like button became shorthand for digital engagement, it was just a quirky cartoon: a thumbs-up meant to show support. Reeves and Goodson peel back the curtain on its creation, introducing readers to a cast of tech luminaries—founders from Yelp, PayPal, YouTube, Twitter, LinkedIn, Gmail, FriendFeed, and more.
What struck me most was how unintentional and messy the process was. The like button wasn’t the result of a master plan; it emerged organically, shaped by user feedback, late-night coding sessions, and the serendipity that often accompanies true innovation. If you’ve ever assumed that Silicon Valley’s biggest hits are always meticulously engineered, this book will challenge your assumptions.
The Power of Serendipity in Innovation
Here’s why that matters: Innovation often isn’t a straight line. The like button’s journey—from brainstorm to beta to viral adoption—reminds us that even world-changing ideas can start as afterthoughts or side projects. The authors draw parallels with other iconic inventions, showing that timing, culture, and a bit of luck are just as important as technical prowess.
The Science Behind the Click: What Makes “Like” So Addictive?
A Cocktail of Psychology, Evolution, and Business
Why do we crave likes? It turns out, this isn’t just digital vanity—it’s hardwired into our brains. The book draws on social psychology, neuroscience, and even evolutionary biology to explain our obsession. Think of the like button as a digital dopamine dispenser. Each tap triggers micro-rewards, reinforcing behaviors and making platforms stickier.
Key insights from the book:
- Social validation: Humans are social animals. The like button offers instant, quantifiable feedback—a digital “nod” from our tribe.
- Habit formation: Frequent positive feedback (likes) keeps us coming back, almost involuntarily.
- Network effects: The more people use the feature, the more indispensable it becomes—a classic example of cumulative advantage.
Let me explain how this plays out: Imagine posting a photo. The likes start rolling in. You feel a tiny rush. Next time, you’re more likely to share—hoping for another hit of approval. This feedback loop is no accident; it’s engineered, and it’s incredibly powerful.
From Anthropological Roots to Algorithmic Futures
Reeves and Goodson don’t stop at the surface. They trace the thumbs-up back to ancient gestures of approval, connecting dots from gladiator crowds to Roman emperors. Fast-forward, and you see how the same instincts are now amplified by AI-powered algorithms, shaping what we see and what we value—sometimes for better, sometimes for worse.
The Business Impact: How the Like Button Fuelled a New Digital Economy
Turning Attention Into Currency
One of the book’s most compelling chapters explores how the like button didn’t just change user behavior—it rewrote the rules of business. By quantifying engagement, social platforms could suddenly track, monetize, and even manipulate attention.
Here’s a quick breakdown of its business implications:
- Data-driven growth: Likes became signals for algorithms, helping platforms surface popular content and keep users hooked.
- Viral marketing: Brands began crafting content specifically designed to earn likes, giving rise to influencer culture and meme marketing.
- Monetization: Advertisers flocked to platforms where engagement could be measured and optimized in real time.
The result? A booming attention economy—where “likes” are the new currency, and every tap feeds a multi-billion-dollar ecosystem.
Lessons for Innovators and Leaders
The like button’s story is a crash course in product design, network effects, and the unforeseen consequences of even the simplest features. Reeves and Goodson illustrate how small design tweaks can cascade into massive social shifts—a lesson every entrepreneur and product manager should take to heart.
The Dark Side: Unintended Consequences of a Simple Feature
Addiction, Anxiety, and the Battle for Our Attention
Of course, no innovation comes without a shadow. The authors aren’t blind to the dark side of the like button. What began as a fun way to give feedback quickly morphed into a source of anxiety, FOMO, and even addiction. Teens and adults alike now measure self-worth in likes, while social media companies fine-tune algorithms to keep us scrolling.
Here’s why this matters: The like button, while empowering, has also contributed to issues like cyberbullying, polarization, and mental health struggles. The book doesn’t preach, but it does ask hard questions: What responsibility do designers have for unintended consequences? Can we “un-invent” features that go viral—and should we?
Rethinking Digital Design for a Healthier Future
Reeves and Goodson argue for more mindful design—urging tech leaders to balance engagement with ethics and well-being. They spotlight emerging trends, like platforms experimenting with hiding like counts or promoting healthier online habits.
For readers, these stories are both a warning and a call-to-action: We all have a role to play in shaping digital culture, whether as creators, consumers, or policymakers.
The Human Element: What the Like Button Reveals About Us
The Thumbs-Up as a Mirror
At its core, the like button is more than a tech feature—it’s a mirror reflecting our deepest social needs. We crave connection, acknowledgment, and belonging, whether in ancient Rome or on Instagram. The book’s mix of anthropology, psychology, and business theory makes one thing clear: The urge to be seen and validated is timeless. Technology just supercharged it.
Why This Story Resonates Today
Reading Like, I found myself thinking about the ways I use (and sometimes misuse) the like button. It’s a tool for quick encouragement, but it can also become a crutch or a mask. Reeves and Goodson’s storytelling invites readers to reflect—without judgment—on how we connect, express ourselves, and navigate our increasingly digital world.
