From his NYT column…

In 1994,… Esther Dyson, made a striking prediction: that the ease with which digital content can be copied and disseminated would eventually force businesses to sell the results of creative activity cheaply, or even give it away. Whatever the product — software, books, music, movies — the cost of creation would have to be recouped indirectly: businesses would have to “distribute intellectual property free in order to sell services and relationships.”

For example, she described how some software companies gave their product away but earned fees for installation and servicing. But her most compelling illustration of how you can make money by giving stuff away was that of the Grateful Dead, who encouraged people to tape live performances because “enough of the people who copy and listen to Grateful Dead tapes end up paying for hats, T-shirts and performance tickets. In the new era, the ancillary market is the market.”

Indeed, it turns out that the Dead were business pioneers. Rolling Stone recently published an article titled “Rock’s New Economy: Making Money When CDs Don’t Sell.” Downloads are steadily undermining record sales — but today’s rock bands, the magazine reports, are finding other sources of income. Even if record sales are modest, bands can convert airplay and YouTube views into financial success indirectly, making money through “publishing, touring, merchandising and licensing.”

What other creative activities will become mainly ways to promote side businesses? How about writing books?

He goes on to argue that — via Kindle-type devices — much the same will happen to book authoring. Hmmm…
