Должны ли детские каналы обучать или развлекать эссе на английском

I think, TV shows for children should teach. However, it shouldn't be boring for them. TV channels should have such contant that would include both parts: entertainments and studying. Brains of children are ready to learn new information and that is why they could watch TV and earn some new skills at the same time. In every good movie or cartoon we can find a moral and something new about our world and TV channels should always remember it.
