Marketing is the process of creating a product and selling it to the public, through advertisements and word of mouth (ex. selling new dorito's chips during the superbowl commercial times). Advertising is how you sell a product, whether it be bashing another similar product (ex. honda cars comparison to toyota cars; gas milage and passenger capacity) or just getting it on tv for people to see. Propaganda is how you persuade a person or group to make a decision on certain topics (ex. our coach brought in new balance, adidas, and nike reps to show us the gear we could wear for the season; sweats, travel gear, shoes, jersey's, etc.) We decided as a group after being told and show what we could have.
