How many hours a week does your family spend in front of the TV? What do you think you and your family would do if there was no TV? TV is important to us because as human beings, we do need distraction from our work, our responsibilities, our chores, etc. What we forget is that while it is very convenient, TV is not the only source of distraction.
There are many other sources of distraction that are just as enjoyable, maybe more. Besides, unlike TV most other sources of distraction like playing games, taking up a hobby or reading help make us a better adjusted human being.
