Theoretical developments of superconductivity after the GL and BCS theories are reviewed. Three issues are discussed in particular: (1) why superconductivity is observed in so many materials and (2) to what extent superconductivity is rich in nature and (3) how the repulsive Coulomb interaction can realize superconductivity.

I present here the past and present situations of new superconductors and also the future prospect. Superconductivity has started since Kamerlingh Onnes first observed the zero resistivity. After that, the critical temperature T_c was gradually increased. In the early stage of superconductive material investigations, main contribution has been made by B. Matthias and his group. In 1986, a new superconductor La-Ba-Cu-O, which belongs to new category in the superconducting society, has been found by Bednorz and Muller. After that T_c's have been drastically increased, and finally reached to T_c〜164K in the Hg-compound. Next, I review several new superconductors discovered within 20 years. Finally, I mention my personal perspective to a higher-T_c superconductor.

After a brief review of the superconductivity research before 1986, recent experimental progress in the research of the high-T_c cuprates is overviewed. High-T_c superconductivity has changed landscape of physics of superconductivity as well as condensed matter physics by stimulating a rapid development of advanced spectroscopies. They continue to reveal unusual properties of both normal and superconducting states, such as coexistence of competing orders and strong quantum fluctuations. However, new mysteries of high-T_c superconductivity emerge from these experimental findings.

The history of the superconductivity research is reviewed from a view point of how the phase of the superconducting order parameter has been recognized and controlled. The concepts of macroscopic quantum coherence and quantum computing have stimulated the progress towards quantum-state manipulation of artificial systems in electrical circuits.

The theory of spontaneous symmetry breaking in particle physics was proposed by Yoichiro Nambu, inspired by the idea of the BCS theory of superconductivity. Since then, Nambu's idea has become one of the main theoretical ideas in particle physics, while the details of the symmetry breaking in Quantum Chromodynamics remain a difficult problem as it requires non-perturbative methods to analyze. More recently, numerical simulation based on lattice gauge theory has revealed its microscopic mechanism.

Research and development of materials technology over many years are required from the discovery of superconductors to reach their practical applications. There have been many technical hurdles for copper-oxide high-temperature superconductors discovered a quarter century ago because of their peculiar physical properties. Nonetheless, mass production of superconducting tapes with kilometer length has recently been realized, and developments of electric power devices such as superconducting cables and industrial equipments utilizing such tapes have really started. As for electronic applications, developments of large-scale integrated circuits based on low-temperature superconductors and applications of highly sensitive electromagnetic wave sensors to science have steadily progressed these years. For copper oxides, developments aiming at industrial applications of integrated superconducting quantum interference devices with high performance are in progress.
