Through creative advertising techniques wants can become needs. These factors also can increase by the demographic background of the consumer. Higher income brackets create demands for more needs while lower income consumers may only grow to a want status. With an effective enough advertising campaign through social groups a taste can indeed be changed and influenced.
Companies who advertise on the web are usually charged via major credit card although in some exceptions there may be other payment options such as PayPal, M.O., or check.
Propaganda is different than persuasion. A propagandist is only interested in achieving his goals. Persuasion involves a dialogue between two parties. If I'm attempting to persuade you, I make my goals clear, state my case, listen to your concerns, adjust my goals as necessary, etc. Ideally, both sides win.
That's not the case with propaganda, which is one-sided with the goals of the propagandist concealed. A propagandist attempts to achieve his goals at all costs.
