Advertising and Graphic Design have a very strong relationship and often have to work together. They are very similar fields. The main differences between the two are Graphic Designers look to tell you about their own personal ideals and views and Advertisers look to find a way of making what they are selling part of your ideals and views. The way in which advertisers and Graphic Designers work together is the advertisers will come up with a concept or idea and the graphic designer will make that idea a reality. However in Graphic Design there is a lot more freedom for self-expression as you can be free-lance. In Advertising you can be creative but as long as it appeals to the demographic.
