I think the Jackson to Jackson haul at 290 miles is the longest I have read about.
But I know Gannett just moved Palm Springs to Phoenix, which is 280 miles. Gannett also owns Ventura. Does Ventura print in Phoenix? That is a distance of 453 miles.
I used to hang around the Denver Post circa 1974. It was explained to me that with the technology of the day the paper had to basically be produced on-site, given the deadline pressures. But no more.
That is why I think the number of newspapers in this country will decline to 100 or so. Papers are consolidating printing at such a rapid rate that only a few plants will be left. And once the physical product is printed at the same place it is cheaper to combine the websites and produce a single editorial product.
Google says Ventura is printed by the LA Times but that was a 2017 article, so that may no longer be accurate.
At an old shop, the company invested in some cutting edge technology that allowed pages to be transmitted wirelessly and the newsroom moved to the old corporate HQ, while the press stayed behind. That was 21 years ago. Then they paid to have a T-1 line installed that allowed the copy desk in one town to build the pages for another paper owned by the company about 50 miles away. And, in a true story, one of the deskers there later went on to work for Gatehouse and used that experience to pitch then build the design hub they have/had in Austin. With the Gannett purchase, I don't know or care if it is still open.
The T-1 line was a daily adventure as sometimes it just wouldn't work and the PDFs had to be copied to a flash and driven to the other paper. The wireless connection was much better but it even it had some occasional hiccups but that was much more manageable.
As for the 100 papers, I think Gannett is already there. If you were in Tennessee and driving across the state and bought a copy of each Gannett paper, I think you'd have very few pages that were much different. So, essentially, they're just zoned editions of a Tennessee daily with a different fronts, a jump page or two and a local news page. So if the daily page count was 24, you might have 16 that are exactly the same, with the remainder zoned to each city/region.
So, for sports, everyone wants the Vols and the Titans and because of deadlines they aren't covering high school sports live. As for news, deadlines have wiped next day coverage of local meetings and such, so, essentially, that means no breaking news in print and putting together dummies for just a handful of pages would be comically easy for the experienced. But since all these people have, for the most part, got gone, the struggle is, I suspect, very real.
