Prediction questions
- Which of these five disruptions surprised you most — and which did you see coming?
- The article says incumbents "dismissed the threat as marginal." Why do you think large, successful companies so often make this mistake?
- Can you think of an industry today that feels "safe" from disruption — but probably isn't?
Five Industries Experts Said Would Never Be Disrupted — And What Happened Next
In 2000, Blockbuster had 9,000 stores worldwide and turned down an offer to buy Netflix for $50 million. By 2010, it had filed for bankruptcy. In the same decade, Nokia — which held 40% of the global mobile phone market — dismissed the iPhone as a niche product for tech enthusiasts. Within five years, its mobile division had been sold to Microsoft at a fraction of its former value. The taxi industry spent decades protected by regulation and licensing, convinced that its business model was untouchable. Uber launched in 2010 and within a decade had fundamentally changed urban transport in over 60 countries, without owning a single vehicle. Retail banking was considered one of the most defensible industries in the world — heavily regulated, deeply trusted, and technically complex. Then came fintech. Companies like Revolut, Stripe, and Wise built products that millions of people prefer over their traditional bank for everyday transactions, moving faster and with far lower fees. Perhaps most surprisingly, the hotel industry — dominated by global chains with decades of infrastructure and brand investment — was disrupted by Airbnb, a company that owns no property and launched in 2008 during a global financial crisis. The pattern across all five cases is the same: the incumbents saw the threat, dismissed it as marginal, and continued optimising for the world as it was — not the world as it was becoming.

How Disruption Actually Works
Jigsaw Reading
Fragment A: Disruption Starts at the Bottom
Clayton Christensen's disruption theory makes a counterintuitive argument: the most dangerous competitors are not the ones attacking your best customers — they are the ones serving customers you have ignored. Disruptors typically enter at the low end of a market with simpler, cheaper products that established companies dismiss as inferior. While incumbents focus on their most profitable customers, disruptors improve quietly. By the time the threat becomes visible, it is often too late to respond.
Fragment B: Success Makes You Vulnerable
The companies most likely to be disrupted are often the most successful ones. They have refined processes, loyal customers, and strong margins — all of which create powerful incentives to keep doing what works. Investing in a disruptive technology that might cannibalise your own products feels irrational when the existing business is profitable. This is what Christensen called "the innovator's dilemma": the very capabilities that make a company great at sustaining its current business make it poorly equipped to lead the next one.
Fragment C: Speed Matters More Than Perfection
The companies that win in disruptive markets are rarely the ones with the most polished product at launch — they are the ones that learn the fastest. Amazon, Google, and Spotify all launched products that were incomplete, sometimes buggy, and frequently criticised. What they shared was a relentless commitment to iteration: releasing, measuring, learning, and improving faster than any competitor. In disruption, a good product shipped today consistently beats a perfect product shipped in two years.
Fragment D: Not All Innovation Is Disruption
The word "disruption" has become so overused in business that it has almost lost meaning. A new app feature is not disruption. A faster delivery service is not disruption. True disruption changes who can access a product or service, how much it costs, or how it is fundamentally used — in a way that makes the old model obsolete. Most companies that claim to be disrupting their industry are actually just improving it. The distinction matters because the strategic response to genuine disruption is very different from the response to incremental improvement.
Comprehension questions
- Fragment A says disruptors start at the bottom with "inferior" products. Can you think of a product that seemed inferior at first but eventually replaced something better?
- Fragment B describes "the innovator's dilemma." Has your company or industry ever faced this — where improving the existing product felt safer than investing in something new?
- Fragment D says most companies claiming to "disrupt" are actually just improving. Do you agree? What's a recent example either way?

Innovation Phrases: Speaking Challenge
Speaking Challenge
Use each phrase to talk about innovation, disruption, or change in your own industry or company.
The Disruption Decision
Mission Briefing
Scenario
RetailCo is a profitable mid-size retail chain with 200 stores. A new AI-powered competitor has just launched online with prices 30% lower and same-day delivery. The leadership team has one week to agree on a strategic response.
Chief Executive Officer
You founded RetailCo 20 years ago. You believe the brand's physical presence and customer relationships are still a genuine competitive advantage — but privately you are more worried than you are letting on.
Must use: Listen to all perspectives before deciding. Do not dismiss the threat publicly, but do not panic the team either. You must leave with a clear direction.
Chief Technology Officer
You have been warning about this threat for two years. You believe RetailCo needs to invest immediately in its own digital platform and AI capabilities — even if it means closing some stores.
Must use: Push for bold digital investment now. Do not let short-term profit concerns delay a decision that should have been made two years ago.
Chief Financial Officer
The company is profitable but not cash-rich. A major technology investment would require either debt or cutting the store network — both carry significant risk.
Must use: Protect financial stability. Push back on any plan that lacks a clear ROI timeline. Propose a phased approach rather than all-in investment.
Head of Customer Experience
Your customer research shows that 60% of RetailCo's most loyal customers still prefer in-store shopping — especially for high-value purchases. The physical experience is genuinely valued.
Must use: Defend the in-store model as a differentiator, not a weakness. Push for investment in premium physical experience rather than competing on price or speed online.
