Why does the School discourage TV watching for children?

In the present times, the vast majority of television channels are promoting ideas and behavior that are against the teachings of Islam. Most channels, including cartoon channels that children like to watch, promote immodesty as being “normal”, disrespect as being “cool”, and dishonesty as being “necessary”, amongst other evils. Every single TV show that your child watches has an impact on him/her, and he/she picks up bad habits and negative values instantly. Even if the message is being delivered in a subtle manner, children, quickly and conveniently, pick up foul language from T.V. shows. In addition, children tend to become lazy and fall into procrastination, and waste hours in front of useless television programs. We do realize that television has some good things to offer children, such as news and informational programs, but the risk of the damage done to the children is greater, and may be irrevocable. Hence, we feel that parents should make good programs available to their children in the form of DVD’s, internet videos, and mobile apps, all under their supervision, or at least LIMIT the amount of time their child is watching TV.
