Television news shows are terrible to watch, and I believe they contribute greatly to attention deficit disorder. You have the anchor talking, a ticker with news (usually poorly spelled), stock numbers, and graphics popping up left and right. Stories are short, lack context, and (especially with local news programs) the images are nothing more than filler and played over and over again. Each bit of news is designed simply to be digestible, and encourage no discussion or action.
Read a newspaper, dammit, and learn how to corroborate information.
