Blockbuster had 60,000 employees and a profitable business when Netflix launched. Kodak invented the digital camera and then suppressed it to protect film revenue. Nokia was the world’s largest mobile phone maker when the iPhone launched. None of them were led by incompetent people. They were led by rational people making rational decisions in business models that disruption made irrelevant. Understanding how and why this happens is the starting point for not letting it happen to you.
Disruptive innovation is a concept developed by Harvard Business School professor Clayton Christensen to describe a specific pattern of competitive dynamics: how smaller entrants with simpler, cheaper offerings overtake established market leaders who consistently do everything right by conventional business logic. Understanding the mechanism is essential for strategists, executives, and innovation leaders who need to either drive disruption or defend against it.
Key Takeaways
Disruption, as defined by Christensen in Harvard Business Review, begins at the low end of a market or in new market segments that incumbents do not serve. Incumbents rationally ignore early disruptors because their products are inferior for mainstream customers and their margins are lower. By the time the disruptor improves enough to compete directly, the incumbent has lost the structural advantages needed to respond. Not all innovation is disruptive: sustaining innovation improves existing products for existing customers and does not follow the same pattern.

Disruptive vs. Sustaining Innovation: The Critical Distinction
Disruptive innovation is frequently misused as a synonym for any significant innovation. The original framework is more specific, and the distinction matters because the strategic implications are very different.
Sustaining Innovation
Improves existing products or services along dimensions that mainstream customers value: faster, better, cheaper versions of what already exists. Incumbents are typically good at sustaining innovation because it fits their existing business model, customer relationships, and resource allocation processes. Most R&D investment in established companies is sustaining innovation.
Disruptive Innovation
Initially offers a product or service that is worse on mainstream performance dimensions but offers different attributes: lower cost, greater simplicity, greater accessibility, or new market creation. The disruption occurs because these alternative attributes appeal to customers the incumbent does not serve, or to its least profitable customers, creating a foothold from which the disruptor improves over time.
How Disruption Unfolds: The Typical Pattern
| Phase | What the Disruptor Does | What the Incumbent Does | Why the Incumbent’s Response Is Rational |
|---|---|---|---|
| Entry | Enters at low end or non-consumption segments with a simpler, cheaper offering that incumbents’ mainstream customers would not find attractive | Ignores or dismisses the disruptor; continues serving its most profitable mainstream customers | The disruptor’s product genuinely is inferior for mainstream customers and its margins are unattractive |
| Improvement | Uses profits from the low-end foothold to invest in improving the product, gradually moving upmarket | Continues to cede the low end as unprofitable; focuses resources on high-margin customers | Margin improvement from ceding the low end looks positive in the short term; moving downmarket would cannibalize profitable business |
| Displacement | Product has improved sufficiently to serve mainstream customers adequately; price advantage brings mainstream customers across | Attempts to respond but lacks the cost structure, technology, or culture to compete at the disruptor’s price point | By this point, the incumbent’s cost structure, decision-making processes, and customer commitments make matching the disruptor’s model nearly impossible without destroying its core business |
Real Examples Across Industries
Digital Photography vs. Film
Kodak invented the digital camera in 1975 but suppressed it to protect film margins. Digital initially produced inferior image quality for professional and serious amateur photographers. As quality improved, the mass market shifted. Kodak filed for bankruptcy in 2012.
Online Retail vs. Physical Retail
Amazon began with books, a category where price comparison is easy and physical store advantages (browsability, impulse purchase) are limited. As logistics infrastructure improved and customer trust grew, the model expanded across categories. Physical retail’s cost structure could not match the margin equation.
FinTech vs. Traditional Banking
Payments, lending, and wealth management were initially disrupted at the edges: underserved customers, niche products, and digital-native use cases. As FinTech companies improved and built regulatory compliance, they began competing directly for mainstream banking relationships that incumbent banks had previously taken for granted.
Online Learning vs. Traditional Education
Online learning initially addressed non-consumption: people who could not attend traditional institutions due to cost, geography, or scheduling. As quality improved and employer acceptance grew, it began competing for students who would previously have chosen traditional pathways. Professional training is directly affected by this dynamic.
How Organizations Can Prepare and Respond
McKinsey’s research on innovation identifies that organizations which successfully navigate disruption typically do several things that organizations that do not survive disruption consistently fail to do.
The innovator’s dilemma in practice: The core challenge is not identifying that disruption is occurring. Most incumbents can see it. The challenge is that the rational short-term decision for an incumbent, defend the profitable core and cede the unprofitable low end, is exactly the wrong strategic decision for long-term survival. Overcoming this requires organizational design choices and governance structures that allow disruptive initiatives to be funded and protected from the resource allocation pressures of the core business.
The four organizational responses that most consistently work are as follows. Creating separate units with different cost structures, metrics, and cultures to pursue disruptive opportunities, rather than trying to incubate disruption within the core business which inevitably starves it of resources. Monitoring non-consumption segments actively, since disruption most often begins where the incumbent is not competing rather than where it is. Making asymmetric bets through venture investment or acquisition in disruptive startups, gaining exposure to the technology and business model before it threatens the core. And building organizational ambidexterity: the capability to simultaneously optimize the core business and explore disruptive opportunities, which requires specific leadership capability and governance design that most organizations have not developed.
Innovation initiatives that cut across existing organizational silos require the cross-functional leadership capability covered in our guide on cross-functional collaboration.

Frequently Asked Questions
Is all innovation disruptive?
No. Most innovation is sustaining: it improves existing products for existing customers. Sustaining innovation is valuable and necessary, but it does not follow the same competitive dynamics as disruptive innovation. The strategic challenge is distinguishing between improvements to the core (sustaining) and threats from adjacent or lower market segments (disruptive) so the organization allocates resources to both appropriately.
Can incumbents successfully disrupt themselves?
Rarely, and almost never from within the core business unit. The few incumbents who have successfully disrupted themselves, Netflix transitioning from DVD rental to streaming, Amazon expanding from retail to cloud computing, did so by creating genuinely separate units with different business models, or by acquiring disruption capability rather than building it in the core. The barriers are organizational and cultural as much as strategic.
What industries are most vulnerable to disruption currently?
Healthcare, professional services (including legal and accounting), education, financial services, and logistics are undergoing significant disruption driven by AI, digital platforms, and changing customer expectations. The common thread is that these industries have historically depended on information asymmetry, regulatory protection, or physical distribution advantages that technology is eroding.
How does AI relate to disruptive innovation?
AI is both a disruptive technology in its own right and an enabling technology for disruption across many industries. It reduces the marginal cost of expertise (disrupting professional services), enables new business models (disrupting established value chains), and allows new entrants to match or exceed incumbent capabilities without the scale that previously protected incumbents. AI disruption is following the classic Christensen pattern in several professional service markets.
How should organizations build a culture that supports innovation?
Innovation culture requires psychological safety (people can raise and test ideas without fear of failure), resource allocation mechanisms that fund exploration alongside exploitation, leadership modeling of experimental behavior, and performance metrics that reward learning from failure as well as successful outcomes. Culture change of this depth requires sustained leadership commitment and structural changes, not just innovation programs or hackathons.
