According to internet guru Clay Shirky, Americans watch roughly two hundred billion hours (200 000 000 000) of TV every year. That represents about 2000 Wikipedias’ projects worth of free time annually assuming that it took one hundred  million hours (100 000 000) of human thought to build it.

If we could recuperate only half of these hours doing something more useful for our society, we would recuperate 28,6 billion days.
