Let’s say you’re Rompetrol, a company which, mainly, produces and sells gas. There are quite a few sellers. How to differentiate? You create a gas (Efix) which is different than others. Not much, but enough to make a small difference. You advertise this, and you can sell this gas with a premium. After all, you’re the sole distributor.
You create, thus, your blue ocean. You don’t compete with others, you have created a market for yourself. Good strategy.
