The Annenberg School at USC does have a unique program in Digital Social Media. However, it’s an MS program – not something you major in as a undergraduate.

The average age of matriculating students in this program is 28, and they average 5-6 years of prior work experience. So get a good undergraduate degree with as little debt as possible, then get some relevant work experience, and save some money. At that point, the Digital Social Media program at USC may be a realistic option for you.
