This is pretty interesting but may not be so relevant in the context of digital products or doing a startup. Yes, we want our products to be mass market from day 1 but if your low-capital 2-person company can get traction in a 1% niche market then you'll have money to focus, retarget, and grow to 2%, 4%, 8%. Pepsi, on the other hand, needs to pay for inventory, shelf space, marketing, and distribution so their profit margins probably depend on mass market adoption. They're also in a position where it's more profitable for them to just axe less popular products and try again rather than steal shelf-space and mindshare from their big sellers.
