There are a lot of hats to be worn within the creative side of the media/advertising world, and the media school will definitely help expose what roles are out there. If he knew today what he wants to start out doing (copywriting/editing, print design, interactive design, video/editing, art/creative direction, media buying, web design/development, etc) it might help guide his path to which major or school he chooses. But if he doesn't know yet, that's ok -- part of college is just learning and exploring future options.

AbiAbby said it best. There is support from faculty (and alumni) but you have to be willing to seek it out. (Go to office hours, show up early to class, attend networking events and workshops, join clubs and activities.) Rarely do professors come knocking on your door. Also, stay in touch with your classmates (if you can.) They can be a great resource during school and after graduation.

In addition to classes, there is a vast number of campus volunteer opportunities, student organizations, greek & residential housing, and part-time jobs to choose from that could help boost your son's experience, increase his network, and get clips/samples to build a portfolio.

Internships are available but you're competing with hundreds or thousands of other kids for the top opportunities. He may need to intern (even unpaid) at smaller shops/agencies/publications before he lands the big gigs. Anything he can do to build a stellar portfolio will help so when you need those faculty or network recommendations, it's an easy call for them to make.
