1. I think broadcasting advertisement are regulated in a way that standards are expected in certain advertising company that you are in. This could be done by the company having a contract for the employee have to sign to follow.

2. BCAP Code
5, 3, 1, 6, 33, 2, 15
5.4 - Advertisements must not condone or encourage bullying. This should be for the brief as the advert should not promote bully for the children to copy and think its acceptable.
If it includes a price, an advertisement for a children's product or service must not use qualifiers such as "only" or "just" to make the price seem less expensive. This should be considered because children are more influenced to persuade their parent because the advert as leaded them to think that it is accessible and cheap to get the product.
3.5 - Subjective claims must not mislead the audience; advertisements must not imply that expressions of opinion are objective claims. The company should not force opinions of the product on to the children, the children should have a genuine interest to the product. This will influence the child who would want to purchase the product because they would have thought the product was as good as the children in the advert have shown it to be.
6.1 - Television only With limited exceptions, living persons must not be featured, caricatured or referred to in advertisements without their permission. The parents need to give consent for the children to be in the advert as they are under age.
5.9 - Advertisements must not include a direct exhortation to children to buy or hire a product or service or to persuade their parents, guardians or other persons to buy or hire a product or service for them. Children will not be the ones buying the product and the product is not directed to the parents. Therefore the product should not direct the children to buy it.

3. The ASA makes sure ads across UK media stick to the advertising rules (the Advertising Codes). They are responsible for monitoring adverts and to take action to ban adverts that don’t follow the rules.
Adverts in the UK are regulated through the system of ‘self-regulation’; the ad industry writes rules through CAP that advertises have to follow and ‘co-regulation’; is an arrangement the ASA have with regulator, Ofcom. On a day to day basis they have to regulate TV and radio advertising.
This overall relates to the BCAP code because it gives people in the media industry a set of rules to follow so they don’t upset owners of other products and mislead or misuse customers to buy into their products. If these rules are not followed the media product of the company is taken down and the company therefore can’t make any further profit .
It is the production company’s responsibility to read and follow the BCAP code so that they are aware of the rules before they start making an advert and also to ensure that through the process of production the are not breaking the rules.
To conclude, I am surprised that there is many precautions you have to make regarding making an advert because your advert may not be able to produced and make profit. Also, there is many rules for each segment that may be included in an advert like health and safety, children's requirements and they way advertisers should advertise.
