Ad Age's A Sign of Things to Come? mentioned that the city of São Paulo banned outdoor advertising, and the movement is picking up steam elsewhere.

São Paulo made history by banning ads on billboards, neon signs and electronic panels, and now Rio de Janeiro is considering a similar measure.

Advertising on the web is not yet heavily regulated, but what happens to the value of domain names or other web assets if certain forms of internet advertising become illegal? I would expect it would increase the value of names, clean traffic streams, and things that operate similarly to public relations while squeezing the margins on less organic forms of marketing and advertising.
