This might sound strangely familiar:
Imagine prisoners who have been chained since their childhood deep inside a cave: not only are their arms and legs immovable because of chains; their heads are chained in one direction as well so that their gaze is fixed on a wall.That allegory is actually over 2300 years old. It from Plato and is known as the Allegory of the cave.
Behind the prisoners is an enormous fire, and between the fire and the prisoners is a raised walkway, along which puppets of various animals, plants, and other things are moved. The puppets cast shadows on the wall, and the prisoners watch these shadows. Behind this cave there is a well-used road, and upon this road people are walking and talking and generally making noise. The prisoners, then, believe that these noises are coming directly from the shadows they are watching pass by on the cave wall...
Suppose a prisoner's chains break, and he is able to get up and walk about (a process which takes some time, as he has never done it before). Eventually he will be compelled to explore; he walks up and out of the cave, whereby he is instantly blinded by the sun. He turns then to the shadows on the floor, in the lakes, slowly working his way out of his deluded mind, and he is eventually able to glimpse the sun.
Meanwhile, in the Modern World, TV is still the leading source of news in the USA. But it's not all bad news:
Pew said the results show an increasing shift toward online news consumption, but that there is now a sizable group of a more engaged, sophisticated and well-off people that use both traditional and online sources to get their news.
The Pew researchers referred to these people as "integrators," and says they account for 23 per cent of those surveyed, spending the most time with the news on a typical day.
