How to actually spot and fix marketing myopia in your business
Theodore Levitt's 1960 Harvard Business Review paper is one of those things everyone cites and almost no one applies correctly. The core idea is simple: companies fail when they define their business too narrowly. Railroad companies didn't lose to other railroads. They lost because they thought they were in the rail business instead of the transportation business. That framing error is what he called marketing myopia. Most people read that paper and think it means you should just broaden your vision. That's not useful advice. It's a diagnosis, not a tool. The practical work is figuring out whether your company's self-definition is actually narrowing your growth, or whether you're just using the concept as an excuse to chase every shiny opportunity.
Marketing Myopia Theodore Levitt
The paper itself was titled simply "Marketing Myopia" and it came out in September 1960. Levitt was arguing that American industry was suffering from a short-sighted view of what customers actually needed. He pointed at industries like steel, oil, and photography and showed how each one assumed its product category was permanent when the real demand kept shifting underneath it. Kodak didn't die because film disappeared. It died because the company believed it sold film instead of preserving memories. Here's the thing most guides leave out. Marketing myopia isn't just about big corporations. It shows up in small businesses all the time. I ran into this with a client back in 2019. They made industrial seals and gaskets for the HVAC sector. Revenue was flat for three years. Every proposal we looked at focused on making better seals. Better materials, tighter tolerances, lower defect rates. We were optimizing a product category that had a hard ceiling. The breakthrough came when we stopped asking what the company sold and started asking what problem it solved. The answer wasn't "seals." The answer was "preventing air leakage in climate control systems." Once we reframed it that way, the competitive landscape changed completely. We weren't competing against other seal manufacturers anymore. We were looking at airflow management, duct sealing solutions, and building envelope diagnostics. The client pivoted toward whole-system leak detection and retrofit packages. Revenue doubled in fourteen months. Not because the seals got better. Because the definition got wider.
The workaround I used was brutal but effective. I made them write their company mission statement three times. First version: what we currently say we do. Second version: what we actually do, based on what customers buy. Third version: what economic need we fulfill that would still exist if our current products became irrelevant overnight. The gap between version two and version three is where marketing myopia lives. There are some counter-intuitive angles here that people miss. First, expanding your definition too far is its own kind of failure. If you say you're in the "human mobility" business instead of the "car business," you'll start making electric planes and probably go broke doing it. The trick is finding the right level of abstraction. You want enough breadth to see adjacent opportunities, but enough constraint to stay focused. The railroad example works because transportation is the natural level up from rail. Going one level further and you're in "logistics" or "supply chain management," which is a completely different operational world. Second, marketing myopia isn't only a strategic problem. It's an organizational one. Companies don't fall into narrow definitions because executives are stupid. They fall into them because their incentive structures reward specialization. Your sales team gets commissions on the product line they've always sold. Your engineering team gets promoted for deepening expertise in the current technology. Your finance team reports margins by product category. Every system in the organization reinforces the narrow view. Fixing marketing myopia requires changing how people are measured, not just what they're told to think about.

The downside of the Levitt framework is that it doesn't tell you when to stop widening your definition. There's no decision tree. No quantitative threshold. You could spend five years and millions of dollars chasing opportunities that seem adjacent but actually dilute your core competence. I've seen it happen. A mid-size packaging company in 2021 read the same HBR article, decided they were in the "material containment" business, and spent eighteen months developing biodegradable shipping solutions for a market that wasn't ready and couldn't profitably serve them. They came back to their original business two years later with eroded margins and a confused brand. If you want to test whether your company has marketing myopia, run this diagnostic. Take your top three customers and ask them to describe the problem they hired you to solve in their own words. Don't let them use your product category. If their descriptions vary widely or reference problems you don't currently address, you're likely too narrow. If they all describe the same problem that aligns with what you sell, you might be fine, or you might just have a very stagnant customer base. The paper itself is about ten pages long. It's freely available through Harvard Business Review's archive or various academic repositories. The full title is "Marketing Myopia" and it's cited in basically every introductory marketing textbook. But reading it won't help you much unless you apply the diagnostic above to your actual business situation with real data, not just assumptions.
Another angle worth considering: marketing myopia can actually be a competitive advantage in some cases. Companies that deliberately stay narrow often outperform those that chase breadth. A local bakery that refuses to expand into packaged goods or franchising will usually be more profitable per square foot than one that tries to be everything. The question isn't whether narrowness is bad. It's whether your narrowness is a choice or a blind spot. Blind spots cause strategic surprise. Choices can be revised deliberately. I should also mention that Levitt's framework predates digital business models by decades. The original examples all involve physical products and commoditized industries. Applying it to software-as-a-service or platform businesses requires adjusting how you think about the "product" versus the "need." A company that sells invoicing software isn't necessarily in the invoicing business. It might be in the cash flow visibility business. That reframing opens up entirely different competitive moves, like integrating payment processing, forecasting, or lending. But it also opens up the risk of spreading too thin across features that don't connect. The practical takeaway is that you should run the three-version mission statement exercise quarterly, not just when things are going badly. Marketing myopia develops slowly. By the time revenue starts dropping, the narrow definition has usually hardened into company culture. Catching it early means catching the symptoms: sales cycles getting longer, win rates declining against unconventional competitors, customers asking for capabilities you've never considered building.
If none of this applies to your situation because you're small enough that your founder still talks to every customer directly, then don't force it. The framework exists for organizations where the gap between leadership's self-perception and market reality has grown large enough to matter. For those organizations, it's one of the most useful diagnostic tools in the marketing canon.
