I'd agree about movies but that, I think, is mostly due to technological changes. Books can take longer. Not fiction but some, philosophy probably, are simply ahead of their time. But that's about making a profit, not about incentive. I do believe that if a person doesn't expect to make a good profit within 20 years they probably won't make the investment. Assuming they care about profit.
