Simply put, it's understanding how the media works, what messages it conveys to us, and what effects it has on all of us as consumers of video, audio and printed materials.
Television can have a strong influence on children.
Therefore, it is important that children and parents understand how to get the most from it. By the age of three, most toddlers have a favourite television show. But at that age, they don't understand the difference between fantasy and reality. Get the whole family to help make a plan on how to manage television watching. Jointly work out the ground rules for which types of programs are acceptable in your family and why.
