On last Tuesday’s edition of the New York Times podcast The Daily, reporters Michael Barbaro and Matthew Rosenberg discussed the Washington Post‘s resounding scoop the evening before: During a meeting at the White House last week, President Trump had revealed classified information to Russian officials.

Rosenberg, who covers national security and intelligence for the Times, was effusive with praise for the rival news organization: “Hats off to our colleagues at the Washington Post who broke this story,” he told Barbaro. “It is a stunning story, and I’m just glad we were able to quickly match it.”

Rosenberg’s use of the verb “match” hearkens back to one of American newspapering’s oldest traditions: Reproducing a rival’s big stories with your own reporting, or “matching.” Like travel agencies and car dealerships, matching persists despite technological advances that should have logically killed it off long ago–in this case, the hyperlink. Why not have your staff work on new stories, the thinking goes.

But Trump’s unusual presidency has made matching important in a few ways. The first is that when you’re dealing with a White House where explanations can change by the minute, matching knocks down the administration’s ability to insist a piece of bad press is based on a mistake or misunderstanding. If you’re able to reproduce a scoop, it bolsters the work that went into the first piece. Another is that it can help reporters at the paper that just got beat to dig in and learn more, maybe even land a subsequent scoop that advances the story. Finally, and not inconsequentially, web traffic is vital to both organizations now. Why leave all those readers on the table?

Still, for all these visible signs of a digital economy, you can find vestiges of the print-era competition that spawned matching in the first place in these stories. Neither the Post nor the Times has a clean record when it comes to crediting news organizations who whupped them on a story, and both can be stingy—at least in body copy—when it comes to hat tips. Here’s a look at how just a few of the big scoops since Trump’s inauguration echoed between the rivals:
