Advertising is most prominent in a free market economy .
Advertising also uses social images and appeals to people's psychological and physical needs.
It ranges from content that sells a product to content that persuades people to adopt specific lifestyles. Given this type of impact, some individuals think certain types of advertising should be banned because of the influence of well-produced messages. Politics has also changed with advertising, particularly as political managers learned to master television. Meanwhile, Internet advertising is just emerging. This raises questions about how advertising will fare with new media technologies, and about the implications for old media.
