Get rid of Commercial advertisement altogether. If there is any advertisement, it should be Fact-based ONLY. NO glorification of life-style and propagandizing life improvements, such as sex appeal, fitness. And glamorous people consuming the products or resulting from using products or services.
Unless you can prove any benefits from using a product or service through actual qualified research, do not allow it to be presented in advertisement. Everything should be backed by research to be presented to the public.
