Still, even though tablets will not save weak media companies, they are likely to give strong ones a boost. Charging for content, which has proved difficult on the web, may get easier. Already, people are prepared to pay to receive newspapers and magazines (including The Economist) on the Kindle. The iPad, with its colour screen and integration with Apple’s online stores, could make downloading books, newspapers and magazines as easy and popular as downloading music. Most important, it will allow for advertising, on which American magazines, in particular, depend. Tablets could eventually lead to a wholesale switch to digital delivery, which would allow newspapers and book publishers to cut costs by closing down printing presses.
If Mr Jobs manages to pull off another amazing trick with another brilliant device, then the benefits of the digital revolution to media companies with genuinely popular products may soon start to outweigh the costs. But some media companies are dying, and a new gadget will not resurrect them. Even the Jesus Tablet cannot perform miracles.
