In this article, history, recent development, future perspective of pressure effect on organic superconductors were reviewed. After describing how the organic superconductor was born, pressure-temperature phase diagrams of two representing organic superconductors were introduced. Next we present several examples of various type of the phase diagrams of the organic superconductors that were recently discovered or attracted. Finally, possible strategies for the development of the novel superconductors are mentioned.
