How much free reign does anyone have when it comes to advertisement? I feel that the biggest issue is not only the volume / spam of advertisement, but how much misinformation it projects. If the quantity of advertisement can be curbed in such a way that corporates are more conscious of how much space they have on television with advertisements (time limiting law), as well as what message they can convey, this starts discouraging and treating in-your-face advertisement less of a prioritiezed form of pitching a product.
