> Does payment depend, necessarily, on restriction of copying? No, it does not.
The only other way I can think of is patronage; I produce a work for a patron according to their wishes, and hand it over for a fee, at which point I relinquish any further control.
Isn't this largely what the recording industry and movie studio model is? They front the money to an artist to pay to produce a work and the artist relinquishes further control. In this case the patron is buying the work in order to resell it.
You can sell rights to be the first viewer/reader/consumer. With a world where all digital content is almost free, first-time exclusivity can increase highly its value.
I agree that 'first consumer pays everything' is an option. Hardback books work like this a little -- if you want to read it earlier, you need to pay more.
I don't know that this continues to work for digital goods. Are there examples you're thinking of?
