Newspapers began to have “scoops” (exclusive pieces of information) in the 1870s and 1880s. The question “What’s the scoop?”—“What’s news?” or “What’s happening?”—was cited in print in 1912 and in 1935. American soldiers frequently asked “What’s the scoop?” during World War II.
 
“What’s the scoop?” is also the name of many ice cream shops..
