Wat is 'the value gap' in het auteursrecht?

The value gap concept is mainly used by the business community to refer to “the unexploited potential of a business division to increase the value of the overall organization” [cacm.acm], in IT business) or to describe “weakened links of ownership in an established value chain”. Applied to copyright, the concept aims to tackle the limited appetite of some internet intermediaries, such as search engines and social networks, to properly or sufficiently remunerate rightsholders for copyright-protected content online. This concerns the overarching issue of “digital revenues” and the need for rightsholders to receive a fair share of the revenues generated by the dissemination of protected content online.

The effect on wholesale wellie prices is dramatic.(...) The latest figures from IFPI are $18 to $1. The gap between $18 and $1 is called the “value gap.” It doesn’t mean every YouTube view would be worth 18 times as much overnight, of course, if the legal loophole disappeared. But it shows how effectively an illegal supply chain can depress prices across the entire wholesale market – and drive suppliers to strike desperate deals they wouldn’t otherwise contemplate.
