Copyright enforcement
A slight TD I know but why only the BBC/SKY ?
All the Germans I know here in Spain watch all the German programs on satellite and asking a lawyer about the "Verlagsrecht" or "Urhebericht" on films purchased for legally viewing only in Germany got me a blank look, as did describing "you can't legally have a SKY viewing card in Spain" to him.
Same goes for Spanish films, plenty available for viewing legally "abroad".
