- 1913: "FUN's Word-Cross Puzzle" (Sun, 12/21/1913) by Arthur Wynne in New York World
"Four weeks after the puzzle first appeared, typesetters at the newspaper inadvertently transposed the words in the title to read 'Cross-Word.' For some reason, the name stuck – and so did the puzzle. When the World tried to drop it a few months later, readers were so hostile that the paper reversed itself and decided to make it a permanent feature of the puzzle page instead. Though the puzzles were popular with readers, they were decidedly unpopular with editors. Crosswords were difficult to print and were plagued with typographical and other errors. In fact, no other newspaper wanted any part of them." ~The Best of Uncle John’s Bathroom Reader (BUJBR)
