-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 is called -trente-, the French word for thirty.

For consideration: John 19:30 New International Version (NIV) 30 When he had received the drink, Jesus said, “It is finished.” With that, he bowed his head and gave up his spirit.
