This is the central thesis of Aaker's 2020 book 'Owning Game-Changing Subcategories.' It holds that with almost no exceptions, businesses grow not by being the best in an existing category but by finding and owning a new or improved subcategory built around must-haves customers insist on. Aaker's research across beer, computers, banks, and cars found that market-share trajectories change only when a new subcategory emerges. The most robust finding in marketing is that a new product's success is predicted by how different it is. Winning therefore means making competitors irrelevant rather than beating them on quality.
Origin
Aaker studied 30 years of beer market data in Japan and found the market-share trajectory changed only four times, each driven by a new subcategory such as Asahi Super Dry. He confirmed the pattern across two dozen other categories including computers and banks, concluding that spurts of growth are almost always driven by a new subcategory.
Core principles
- 01Real growth almost always comes from creating and owning a new subcategory, not from winning an existing one.
- 02The single strongest predictor of new-product success is how different it is.
- 03A game-changing subcategory contains must-haves customers will insist on.
- 04Winning is about making competitors irrelevant, not about being marginally better.
- 05Creating a subcategory is far more achievable than creating a whole new category.
How to run it
- 1
Stop trying to be the best in an existing category
Abandon the instinct to win market share by being marginally better than incumbents. Aaker's research shows almost nobody grows their business that way.
Watch out Study after study finds 'better' loses; 'different' wins.

Find a source of genuine difference
Generate a new offering idea from one of two directions: understanding market needs by observing what customers do and complain about, or leveraging your technology and product capabilities.
Pro tip Look beyond your own product class at what people are ultimately trying to get, so you are not trapped in incremental improvement.
- 3
Build in the must-haves
Design the subcategory around must-haves — features so compelling that customers will not consider offerings that lack them.
Pro tip There are usually several must-haves at once, as with the Prius design, functionality, and yearly improvements.
- 4
Own and define the subcategory
Position and scale so you become the exemplar of the subcategory, controlling how customers think about the whole space.
Pro tip Owning the subcategory can grant years of runway — Prius ran roughly 12 years without real competition.
In the wild
Honda released a hybrid first, but Prius was the first to get it right, bundling several must-haves: a distinctive design, hybrid functionality, and continual yearly improvements. This defined the hybrid subcategory around Toyota's terms.
→ Prius ran roughly 12 years with essentially no competition, owning the subcategory it created.
Across 30 years of Japanese beer data the market-share trajectory changed only four times despite huge marketing spend each year. Each shift, such as Asahi Super Dry, came from the discovery of a new subcategory rather than from outspending rivals.
→ The finding confirmed that growth spurts are driven by new subcategories, not by winning the existing one.
Common mistakes
Chasing best-in-category
Trying to be the best in an existing category almost never grows a business; the data overwhelmingly favors creating something different.
Confusing better with different
Incremental superiority gives customers little reason to switch or talk; genuine difference gives both a reason to buy and word-of-mouth visibility.
Is it for you?
Best for
Founders and product leaders seeking uncommon growth by defining a new space they can dominate.
Not ideal for
Firms with no capacity to innovate or differentiate, forced to compete purely on execution within a fixed category.

“the predictor of a success of a new product is how different it is”
“when you create a, some new innovation, you make you win. Not because you're better. It's because the other people are not relevant”
