Kim & Mauborgne: We use the terms red and blue oceans to describe the market universe. Red oceans are all the industries in existence today—the known market space. In the red oceans, industry boundaries are defined and accepted, and the competitive rules of the game are known. Here companies try to outperform their rivals to grab a greater share of existing demand. As the market space gets crowded, prospects for profits and growth are reduced. Products become commodities, and cutthroat competition turns the red ocean bloody. Hence the term red oceans.
Blue oceans, in contrast, denote all the industries not in existence today—the unknown market space, untainted by competition. In blue oceans, demand is created rather than fought over. There is ample opportunity for growth that is both profitable and rapid. In blue oceans, competition is irrelevant because the rules of the game are waiting to be set. Blue ocean is an analogy to describe the wider, deeper potential of market space that is not yet explored. Like the ―blue ocean, it is vast, deep, powerful, in terms of profitable growth, and infinite.
