The difference between marketing, advertising, and propaganda.

When first posed the question in class "what is the difference between marketing, advertising, and propaganda?" I thought they were all the same. After thinking about it after class I realized that they are all the same but with different goals. Marketing, advertising, as well as propoganda all attempt to promote a product or an idea. They hope by making the information available to the public that their product or view point will be attractive to others. It can inform people about things that otherwise would not be known without the use of one of those three means. Marketing seems to be a way to keep people informed about a product that already exsists. This can be thought of when looking at insurance companies. Insurance companies have a product that relies on name recognition, so the continual use of marketing helps keep the name in peoples mind as well as promoting people to use their services. Advertising seems to promote new products. While you can use advertising for old well known products, an advertisement tries to show the public a new product. An example of this product would be when the ipad first came out, advertising was used as a means to introduce the public to the product. Propaganda seems to stand out the most in its differences. While it is showing the public a product it is almost always used as a way to promote political ideals. The movies made by the Nazi's are a perfect example of promoting ideals in interesting ways.
Whether you realize it or not, what type of promotions do you think have made an effect in your life?
