I know that some people refer to the television as an idiot box, honestly, I believe that it depends on the program. There are some programs to help further childrens learning, and of course there are some that are just for entertainment, but its the parents responsibility to authorize what their children is watching. If they don't then I believe they can't sit back and say they blame the media.
Im not saying that the children can learn everything they need to know by just watching TV, because I know that can't happen. Programs such as Clifford, Blues Clues, and Dora can teach how to share, count, and even how to solve minor problems. But, their are limits to what the programs can teach children. And, that's when the parent's or guardians have to step in and take action.
