In 1996 the U.S. government developed the then fastest supercomputer in the world. The project cost about $55 million and occupied a floor space of about 80 percent of a tennis court. The machine reached the power of 1.8 teraflops. Just nine years later another computer hit this benchmark. The difference: It could fit into every living room and cost only about five hundred dollars. The computer was the PlayStation 3, developed by Sony.
