This excellent, illustrated 'beginners guide' radically rewrites the conventional accounts of the waves that rule the world - from Marconi's military-sponsored experiments with the 'wireless', to the growth of state-controlled 'public services' and commercial broadcasting, and on to video, satellite, and cable. The latest technologies can bypass traditional systems of censorship and control, and give media moguls the means to dominate mass communications across the world. Paradoxically, these same technologies also offer the possibility for more open communication. Media & Power documents many examples of democratic broadcasting and suggests ways in which we can reclaim the airwaves.
