Sony Computer Entertainment America has grown the largest console online community in record time. In just over a year, the company attained critical mass with more than one million online gamers. While others struggled to reach this milestone, the company forged a new, more aggressive goal -- to bring 5 percent to 10 percent of the installed base online within the platform's lifecycle. In just eight months of setting that goal, the company surpassed it, having grown the installed base to more than 25 million gamers and bringing more than 10 percent of the massive installed base online.

Engineering Research Associates of Minneapolis built the ERA 1101, the first commercially produced computer; the company´s first customer was the U.S. Navy. It held 1 million bits on its magnetic drum, the earliest magnetic storage devices. Drums registered information as magnetic pulses in tracks around a metal cylinder. Read/write heads both recorded and recovered the data. Drums eventually stored as many as 4,000 words and retrieved any one of them in as little as five-thousandths of a second.

Computers now play a major role in education in the form of computer-based learning systems. Because of their interactive nature, they increase the motivation level of the learner. Learning theories such as Pask , Spiro , and Salomon are particularly relevant to the use of computers for learning. Finally, the work of Seymour Papert (e.g., Papert, 1980;1993) with the LOGO programming language should be mentioned. Papert believes that children can understand concepts best when they are able to operationalize them through writing computer programs. In his formulation of constructionism, technology (including computer games) can play a critical role in helping children learn.
