African mothers were so taken by Nestle's advertising that they gave up breast feeding their infants and fed them formula instead. Since the formula was often diluted and in unsanitized bottles, this caused a lot of health problems. After years of pressure and boycotts from various groups, Nestle finally withdrew their advertising campaigns. The whole point of advertising is to manipulate people's buying habits. It's as direct a form of cultural domination that you can find, and in this case it caused some harm.
Real news is as objective as possible.
There may be biases in it, but they are not deliberately introduced. Propaganda is deliberately slanted towards one point of view. Negative events are ignored, positive ones are played up, and opinions are presented as facts. Small countries are right to be wary of propaganda, because it is a form of political manipulation. It's as if foreign agents were going among their people whispering things in their ears.
