Advertising
Advertising is a non-personal form of mass communication which offers a high degree of control to those responsible for the design and delivery of advertising messages. Though, advertising's ability to persuade the target audience to think or behave in a certain way is suspect. Moreover, effect on sales is extremely hard to measure. Advertising also suffers from low credibility, in that audiences are less likely to believe messages delivered through advertising than they are messages received through some other tools.
