@mjg59 Scaling it by aggregate viewing time would be great.
2 million viewer-hours? Looks like the copyright expired on opening weekend!
@mjg59 Three words: Intellectual Property Tax
After a nominal period of protection, say, 20 years the rights holder may continue protection by paying for it based on a percentage of its estimated worth up until a maximum time limit is reached, say, 100 years.
@mjg59 For some reason, this makes me think of the off-licence by my old flat in Hammersmith. They had a pretty wide selection, and not-so-knowledgeable staff, but whoever did inventory knew what was up.
So the shelves in back were covered in bottles with pretty decent prices on, like maybe £3-5 cheaper than you could get in the neighbourhood. So I'd go in and grab a bottle of something, and the bottle behind it would have a sticker showing about what you'd pay elsewhere. The last row of bottles had a markup.
It was a really simple scarcity-based pricing trick that I once implemented in a priority queue system for some kind of build manager.
@mjg59 I think it's easier to just bill them 1% of cumulative revenue starting the 11th year for each year they want to extend.
So at year 11 you'll pay 1% of first-10y-revenue, then to extend copyright for year 12 you pay 1% on the first 11 years and so on.
Tweak the numbers but this should work. And it creates government employment opportunities to handle the copyright extension filings and billing.
