The Digital Hand, Volume 2 is an historical survey of how computers and telecommunications have been deployed in over a dozen industries in the financial, telecommunications, media, and entertainment sectors over the past half century. It is part of a sweeping three-volume description of how management in some forty industries embraced the computer and changed the American economy. Cortada is one of the premier-and most prolific-of computer historians and covers nooks and crannies that many others miss. Given the present centrality of computers in virtually everything, Cortada is becoming the recorder of a very important transformation in American (and most world) business.
