Did you know that Sao Paolo (Brazil) and Grenoble have banned those hateful billboards and outdoor advertising? Vermont, Main, Hawaii and Alaska are also billboard-free. Tehran, New York and Paris are discussing the possibility to follow the path of these cities. This article from the Guardian represents a good reference.
Take a look at this post from @dougkessler. He lives in London, as I do. And Milan, where I’m from, was (is) the kingdom of those huge building-sized billboards.
And I hate those obscene adverts, too. It’s all but content marketing; it’s pure interruption. And unfortunately, no way to individually opt out…
the way telling us between both type of advertising is true and very easy to understand
