Probably the pumps with the 5x5 screens are still in the minority, the others having a different kind of display which appears to be text only and too small for any useful presentation.
Some stations have the satellite dishes, but they, too, are probably in the minority. Not to mention those (often the least expensive stations) which do not have any provision for pay-at-pump.
As far as revenue from advertising, this would appear to be the only reason for providing such a service. Otherwise, why would any station do it or why would the vendor/supplier even think of going into this business?
