The New York Times sold an article tied to an NFT, or nonfungible token, for about US$560,000, another sign of the red-hot market for digital collectibles.

“Buy This Column on the Blockchain!” from Times journalist Kevin Roose was turned into an NFT and auctioned off on the open market, with the proceeds going to the newspaper’s Neediest Cases Fund, which supports charitable causes.

The actual subject of the column published Wednesday was NFTs, which carry certificates of authenticity proving that online works of art are unique. On March 25, he tweeted that it had sold.
