While billboards are annoying, a) everyone sees the same, they aren't tailored, b) they aren't as ubiquitous, most people don't spend as much time looking at billboards as they do at various feeds and c) they are only show 1 advert, I would say an equivalent to a feed would be every billboard in a part of a city showing an advert that sells the same thing in a slightly different way.
