 | | The case of the QWERTY keyboard is considered first, because it has generated the most controversy and it illustrates opposing arguments. |
 | | David (1986) noted that the QWERTY keyboard was designed, in part, to reduce mechanical jamming on an early typewriter design that quickly went out of use, while other early keyboards were designed more with the intention of facilitating fast, efficient typing. |
 | | Whether the early history of QWERTY was path dependent thus seems to depend largely on the unaddressed question of how much typing instruction was offered directly by suppliers, as Liebowitz and Margolis suggest could have happened, and how much was offered by third parties using QWERTY, as David showed did happen. |
