Media studies majors go on to do all sorts of things (Among MS majors, a couple I knew last year went to Google, law/biz school seems popular, entertainment industry, ...lots of places).
Because Pomona is a liberal arts college, not everyone majoring in a subject will fall into that specific field. (i.e. Math majors going to acting school, molecular-bio majors going into consulting, physics majors going to law school, etc. aren't that uncommon).
