Digital Signage Central

Although interested in signage as a means of information distribution, I wonder if in a lot of cases the systems deployed are fashionable technology in search of an application? This is a cause for concern because of the power consumed by all these screens/processors which are appearing everywhere…

This cylindrical screen has popped-up overnight in the car park of our local shopping centre. It does not appear to be particularly effective, and if you stand close by you can really hear the fans whirring! Probably costs more to run than indirect sales gained.
