What describes televisions greatest social impact

Each of these ideologies has at some point been a major influence in Western society, for instance; nationalism reigned during the war years, liberalism influenced the 60s and 70s, socialism affected the 70s and 80s and in the last 20 years or so the main impacting factor has been democracy, driven by the war in Iraq and the war on terror. So they underly different age groups and aspects of our society and history and provide a patchwork effect to the life of the western world. These ideologies go have appeared earlier in history too and will probably resurge again in the future as each one becomes less "ideal". Hope this makes sense?!?!?!
