内容简介：
This study provides Canada's first comprehensive, integrated treatment of the emergence and development of key communication sectors: telegraph telephones, cable TV, broadcasting, communication satellites, and electronic publishing. By focusing on real institutions, actual (and frequently predatory) business practices, and law and regulatory policies, in both historical and contemporary perspectives, Babe helps demystify current communication issues.Stressing the flexibility of communication 'technologies' on the one hand, and the element of corporate power on the other, Babe reintroduces the principle of corporate/governmental responsibility for communication outcomes, a principle that has been largely drowned out by the shrill cries of 'Information Revolution.'
