Mass Communication

Mass communication studies in college usually consists of a combination of mass communication theories, models, aspects of mass media, journalism skillsets like editing, reporting, newspaper and magazine publication, social media content creation skills, public relations, advertising. This is the usual package.
Visual communication studies have to do with a whole lot of entirely different skillsets, both conceptual and otherwise, relating to graphic design - typography, illustration, text and image, infographics, branding and identity, user interface, posters, web design, publication design, packaging design, sequential art and so on.
These are two different worlds. The area of overlap in the two spaces is publication design for newspapers and magazines and web design if journalistic or similar content is being placed online for readers/viewers. Many newspapers and magazines and webzines have an art direction/design department and that would hire not graduates of mass communication but visual communication.
There is no comparison between the courses. So, you may pursue any of them depending upon your area of interests.
