City enacted an ordinance banning from its public sidewalks all machines dispensing publications consisting wholly of commercial advertisements. The ordinance was enacted because of a concern about the adverse aesthetic effects of litter from publications distributed on the public sidewalks and streets. However, City continued to allow machines dispensing other types of publications on the public sidewalks. As a result of the City ordinance, 30 of the 300 sidewalk machines that were dispensing publications in City were removed. Is this City ordinance constitutional? 
Yes, because regulations of commercial speech are subject only to the requirement that they be rationally related to a legitimate state goal, and that requirement is satisfied here.  Yes, because City has a compelling interest in protecting the aesthetics of its sidewalks and streets, and such a ban is necessary to vindicate this interest.  No, because it does not constitute the least restrictive means with which to protect the aesthetics of City's sidewalks and streets.  No, because there is not a reasonable fit between the legitimate interest of City in preserving the aesthetics of its sidewalks and streets and the means it chose to advance that interest.
