How do I define Marketing, Advertising, and Propaganda?(In my opinion)

Marketing: is the process of selling, pricing, and estimating the projection of sales for a product. Marketing in my opinion is the first part to establishing a new product in a company.

Advertising: is creating consistent circulation of the products to consumers. This is done in various way such as television, ads in Magazines/Newspapers, and on the internet. 

Propaganda: Is a form of biased advertising used to sway a group of people I believe this to be the oldest form of "advertising" based on history regardless of how true it may be. 


*Do you think all Propaganda is Negative?
