In fact, poster printing is done in both the new way(s) and the old
way(s) in the US, just as it is done the new way(s) and the old
way(s) in the UK.
Some billboards are printed on paper, some on vinyl, some on fabric,
some on plastic strips (rotating displays), etc. Some are printed
using inkjet processes, some using photographic methods, some using
screenprint, some using offset litho...
Although some are less common than others, there is *no* single
method or medium.
BTW, Wikipedia is probably better described as the fount of all
rumours, not all knowledge. It is a good resource, but it should
never be regarded as a definitive souce of information; always
cross-check and be ready to reassess or even disregard what's
And in fact a fair amount of what's said in that particular article
makes too-broad assumptions, is misleading or, in some cases, is
simply untrue. It is also missing key information, for example
explanations of 48-sheet or 96-sheet posters/billboards.
