The arts have to be their own reward. If you're making art for money, and not the love, it's probably not worth doing.
For better or worse, the marketplace is finally realizing this.
I'm saying that if money is the dominant motivating factor in producing art, expect to be disappointed. Technology has reduced many costs of artistic production and has led to an oversupply of "content." To the cold, uncaring marketplace, you're effectively being compensated by those good feelings involved in the process of imagining, producing, and sharing art.
Even so, I draw and record music for my own enjoyment, and to collaborate with friends.
But surely you could organize your own precision-strike book or album release via targeted online ads. I'd be surprised if there weren't lots of companies trying to sell this service.
