Regulation

There have been increasing efforts to protect the public interest by regulating the content and the influence of advertising. Some examples are: the ban on television tobacco advertising imposed in many countries, and the total ban of advertising to children under 12 imposed by the Swedish government in 1991. Though that regulation continues in effect for broadcasts originating within the country, it has been weakened by the European Court of Justice, which had found that Sweden was obliged to accept foreign programming, including those from neighboring countries or via satellite. Greece's regulations are of a similar nature, "banning advertisements for children's toys between 7 am and 10 pm and a total ban on advertisement for war toys".

In Europe and elsewhere, there is a vigorous debate on whether (or how much) advertising to children should be regulated. This debate was exacerbated by a report released by the Kaiser Family Foundation in February 2004 which suggested fast food advertising that targets children was an important factor in the epidemic of childhood obesity in the United States.

In New Zealand, South Africa, Pakistan, Afghanistan, Canada, and many European countries, the advertising industry operates a system of self-regulation. Advertisers, advertising agencies and the media agree on a code of advertising standards that they attempt to uphold. The general aim of such codes is to ensure that any advertising is 'legal, decent, honest and truthful'. Some self-regulatory organizations are funded by the industry, but remain independent, with the intent of upholding the standards or codes like the Advertising Standards Authority in the UK.

In the UK, most forms of outdoor advertising such as the display of billboards is regulated by the UK Town and County Planning system. Currently, the display of an advertisement without consent from the Planning Authority is a criminal offense liable to a fine of £2,500 per offence. All of the major outdoor billboard companies in the UK have convictions of this nature.

In the US, many communities believe that many forms of outdoor advertising blight the public realm. As long ago as the 1960s in the US there were attempts to ban billboard advertising in the open countryside. Cities such as São Paulo have introduced an outright ban with London also having specific legislation to control unlawful displays.

Many advertisers employ a wide-variety of linguistic devices to bypass regulatory laws (e.g. In France, printing English words in bold and French translations in fine print to deal with the Article 120 of the 1994 Toubon Law limiting the use of English). The advertisement of controversial products such as cigarettes and condoms are subject to government regulation in many countries. For instance, the tobacco industry is required by law in most countries to display warnings cautioning consumers about the health hazards of their products. Linguistic variation is often used by advertisers as a creative device to reduce the impact of such requirements.
