I guess ever since the remote control came into our hands we have been surfing channels.It is one thing to change channels when the program is boring but spending hours together doing just that watching nothing in particular is not a healthy trend esp in children since it brings down their concentration level and shows a lack of discipline which shows in their other activities and personality as well
This habit is not only peculiar to switching on from one channel to another on T.V. channel. Many cannot concentrate on even on a particular job. I know a man who will log in yahoo for mail but even without reading a single mail will ring his family/ children and then interrupt the talk and walk outside to meet somebody. Before he reaches that somebody, he will come back to office and order tea. Before taking a sip from tea, he will search for some file. While seeing the file, he will remember somebody's birthday and send wishes to him. Thus, he cannot finish anything.
