As a PR and IT&M student, Graphic Design is surely one of the most important thing for our career. It is important because as a PR person, we will have to do a lot of writing and posting, where Graphic Design will be a big plus. A well-designed poster will certainly attract more audience and pull more attention to the poster.
Another field that I majored in is the Web Design, which has more to do with the Graphic Design obviously. It is required for a neat and clear web page to be well-designed so that it is user friendly.
I can not image what web design industry will be without Graphic Design skills, there will be no attractive web page and all the pages we use will be somehow the same, just a stack of information and some hyperlink which lead to another web page.
