-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,[1][2] 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.[3] It was included in the Associated Press Phillips Code of abbreviations and short markings for common use. It was commonly used when writing on deadline and sending bits at a time to be typeset, as a necessary way to indicate the end of the article.[4]

In Quebec, a journalism magazine published by the Fédération professionnelle des journalistes du Québec is called -trente-,[5] the French word for thirty.
