–30–

–30– has been traditionally used by journalists in North America to indicate the end of a story. It is commonly found at the end of a press release. There are many theories about how the usage came into being, e.g. from that number's use in the 92 Code of telegraphic shorthand to signify the end of a transmission in the American Civil War era.

In Quebec, a journalism magazine published by the Fédération professionnelle des journalistes du Québec is called -trente-, the French word for thirty.
