There will eventually come a day when The New York Times ceases to publish stories on newsprint. Exactly when that day will be is a matter of debate. Sometime in the future, the papers publisher said back in 2010.

Nostalgia for ink on paper and the rustle of pages aside, theres plenty of incentive to ditch print. The infrastructure required to make a physical newspaper printing presses, delivery trucks isnt just expensive; its excessive at a time when online-only competitors dont have the same set of financial constraints. Readers are migrating away from print anyway. And though print ad sales still dwarf their online and mobile counterparts, revenue from print is still declining.

Overhead may be high and circulation lower, but rushing to eliminate its print edition would be a mistake, says BuzzFeed CEO Jonah Peretti.

Peretti says the Times shouldnt waste time getting out of the print business, but only if they go about doing it the right way. Figuring out a way to accelerate that transition would make sense for them, he said, but if you discontinue it, youre going have your most loyal customers really upset with you.

Sometimes thats worth making a change anyway. Peretti gives the example of Netflix discontinuing its DVD-mailing service to focus on streaming. It was seen as blunder, he said. The move turned out to be foresighted. And if Peretti were in charge at the Times? I wouldnt pick a year to end print,he said I would raise prices and make it into more of a legacy product.

The most loyal customers would still get the product they favor, the idea goes, and theyd feel like they were helping sustain the quality of something they believe in. So if youre overpaying for print, you could feel like you were helping,Peretti said. Then increase it at a higher rate each year and essentially try to generate additional revenue. In other words, if youre going to make a print product, make it for the people who are already obsessed with it. Which may be what the Times is doing already. Getting the print edition seven days a week costs nearly $500 a year more than twice as much as a digital only subscription.

Its a really hard thing to do and its a tremendous luxury that BuzzFeed doesnt have a legacy business, Peretti remarked. But were going to have questions like that where we have things were doing that dont make sense when the market changes and the world changes. In those situations, its better to be more aggressive that less aggressive.
