Fly, Fly Paper, and LeapPad from LeapFrog SchoolHouse (a division of LeapFrog Enterprises) are respectively a talking electronic pen/educational toy, associated paper printed with a fine mesh of dots that works with a mapping chip to feed data into the Fly's CPU, and an older product that is a cross between a talking book and an educational videogame console. The items were invented by Jim Marggraff, and LeapFrog is the global leader in play-based learning. Technically, the Fly pen is pretty advanced, since it is like a robust PDA in a stylus. The tools should be ideal, says Marggraff, for teaching the tween market many academic subjects. Disney, Upper Deck, and Warners have been sufficiently impressed to sign on the dotted line to develop games for the Fly. Marggraff also sees more uses for the Fly in businesses, for instance, where it could be used as a group computing device or a screenless PDA. His plans include an open architecture that will encourage wider development. Many issues are discussed concerning the potential success of the Fly, including the reaction of the tweens, operation and features of the Fly, hardware and software components, Marggraff's education and background (he has a bachelors in electrical engineering and a masters in computer science, both from Massachusetts Institute of Technology, and formed Cisco's MultiService Switching group), and his launch with Mark Flowers of Explore Technology. In the late 1990s, Michael Miliken convinced LeapFrog to acquire Explore, and Marggraff became the executive VP of worldwide content. Marggraff's first inspiration for an educational toy emerged from his desire to give his son a way to control the process of learning to read letter by letter, phoneme by phoneme, and word by word.
