I'm graduating this year on a bachelor degree in advertising and I am looking for a good university for my masters. It can be anywhere in the world, not just United States. I can speak English and Spanish. I'm looking for the best place.

Some good Masters programs in Advertising and Public relations are at American University (Public Communication), Johns Hopkins (Master of Arts in Communication), and the Academy of Art University (Advertising).

for a listing of schools with Media and Public Affairs, Public Relations, Communication and some Advertising degrees. However, most masters programs are more general (Communication, Public Relations, etc.) than Advertising and would include it.
