Rubik showed his prototype to his class and his students liked it very much. Rubik realized that, because of the cube's simple structure, it could be manufactured relatively easily and might have appeal to a larger audience. Rubik's father possessed several patents, so Rubik was familiar with the process and applied for a patent for his invention. Rubik then set out to find a manufacturer in Hungary, but had great difficulty due to the rigid planned economy of Hungary at the time. Eventually, Rubik was able to find a small company that worked with plastic and made chess pieces. The cube was originally known in Hungary as the 'Magic Cube'.
