Good point, Postman's "Amusing Ourselves to Death" is really a good reference about our "entertaining society" and especially his concept "Information-Action" ratio. As our society is evolving into fast/ephemeral information and often really distanced from our reality. The effect of this irrelevant information which is limiting our real actions.

Another good reading on this topic is the work of Guy Debord especially "The Society of the Spectacle" where is explaining the degradation of social life due to the spectacular media.
