This demonstrates one of the arguments associated with cross-cultural advertising.
Cross-cultural advertising refers to the practice of adapting advertising messages and materials to be appropriate and effective in different cultures. This can involve taking into account cultural differences in values, beliefs, norms, and behaviors, as well as differences in laws and regulations. In the case you described, French law prohibits the use of children in product endorsements, so a company would need to edit any commercials using children if it wanted to air those commercials in France. This illustrates the need to consider cultural differences in advertising, as what may be acceptable in one culture may not be acceptable in another. Other arguments associated with cross-cultural advertising include the need to understand the local market and target audience, the importance of language and translation, and the potential for cultural misunderstandings or insensitivity
