Reflection on ads (in general)

Generally speaking, the controversy in publicity insists on sexual content or on really sensitive problems (like AIDS...).
Publicity has to be appealing to people, specially because it has to convince the consumers to consume.
Printed ads, or commercials have the function to make people desire what they are trying to sell, but in some cases that need of convincing the public leads to an outrageous abuse of seduction.
This excessive use leads to the banishment of many ads, what can create controversy among consumers and companies who make the ads.
