The use of foreign broadcast subscriptions puts publicans like Ms Murphy in breach of UK copyrightlaw because the means by which they screen football is not via the authorised broadcaster - Sky Sports.
In its absence, to comply with U.S. copyrightlaw you would have to keep track, in perpetuity, of all foreign-sourced works in order to avoid inadvertently selling, lending, gifting, donating, or otherwise distributing them without permission from the copyright holder.
