TV Statistics: Britons Spend 9 Years of Life Watching TV
9 Years is quite some time, even in the bigger scheme of things, to spend watching TV. But that is precisely what Britons do apparently (Source) based on a study of 2000 adults.
Other interesting points: Women watch more TV than men, and above 55 is the group that spends the most time watching TV. We had spotted some cord cutting stats in the past - obviously that is a mechanism change and not a habit change.
