In the earlier articles in this series, we covered how, for decades, the fight against piracy has turned on one simple question: was the content copied?
It is the foundation on which much of copyright enforcement has been built. A film is copied. A television programme is rebroadcast. A football match is streamed without permission. In each case the infringement is visible, because the work itself has been reproduced.
The scale of that problem is enormous and still growing: during the 2024/25 season alone the English Premier League says it detected more than 645,000 infringing live streams and almost 900,000 unauthorised recorded clips of its matches 1. Enforcement has kept pace, with coordinated raids such as the 2024 operation that dismantled an illegal service estimated to supply 22 million households across the UK and Europe 2.
