Red ocean strategy refers to competition in existing industries where companies try to gain market share from competitors. This leads to cutthroat competition making the market "bloody red". Blue ocean strategy denotes industries not in existence today where there is vast opportunity for profitable growth. Red ocean strategists focus on outperforming competitors, while blue ocean strategists recognize market boundaries are mental and focus on creating new demand through differentiation and lowering costs. Blue ocean strategy changes market structure to render old competition irrelevant and allows companies to play a non-zero-sum game with high payoffs by expanding demand.
