Advertising sectors are widely nowadays so that some advartisers are doing the target at children and sell the toys and snacks, though some advartisers are want to give useful informations to the children. Parents are worried about the advertisements and they want to give useful informations to their children via advertisements. In my opinion, some of children are provided about their social study via online advertisements so i think that's good ideas. On the other Hand, Selling toys and snacks for children on advertisements are supported to develop children's pleasure.
