Some elements of urban life survive the communications revolution just fine, at least so far.
These columns used to be as ubiquitous as phone booths. But while pay phones are gone the Litfaßsäule remains. Perhaps not on every corner, but on every other, at least in areas of the urban core.
While they are advertisements, they generally have informational content. They’re not advertising Mars bars, but instead pointing to current exhibits or events, though not exclusively. I’m not sure whether there are regulations that prohibit the Litfaßsäule from being used for “mere” advertisements.
If Google owns all “modern” advertisements, this seems to be an area of modern urban life that’s been left untouched by a digital revolution.
