I live on an implicitly ad free island in the Pacific. You might figure out where but I'm being vague for privacy. In any case, I don't believe there is any law against e.g. billboards here, but there definitely aren't any. I really appreciate it. When I've driven in e.g. California I feel so depressed seeing all the billboards.
I lived on an island (not in the pacific) where billboards are completely banned, the height of business signs is limited, and where very, very few public places had any advertisements, even in the "city".
It was wonderful and it's one thing I really miss.
