Advertising is so ubiquitous that it’s almost hard to imagine urban spaces without it. And yet, this is precisely what São Paulo, Brazil (the worlds fourth largest city) has done: in 2007, the city passed an ordinance that put a ban on outdoor advertising. Is this choking off a vital source of revenue for some businesses, or this a progressive step towards uncluttering and decommodifying the urban lifeworld, moving one major city one step away from the ravenous jaws of corporate capital? Has this move beautified São Paulo, or has it turned active space into negative space, and if so, what does that say about contemporary design and architecture? See for yourself, and make up your own mind.
