In journalism, "30" is a symbol that marks the end of a story or article.
It's a simple and universally recognized signal for editors, copy editors, and typesetters that the piece is complete.
The origin of "30" is believed to stem from the days of telegraphy, where the number 30 represented the end of a message.
As journalism transitioned from telegraphs to typewriters, the practice of using "30" as an end-of-story marker persisted.
Today, "30" is still widely used in journalism, although it is becoming less common with the rise of digital publishing and the use of software that automatically marks the end of a document.
While it's no longer essential in digital journalism, "30" remains a recognizable symbol among journalists, representing the completion of a story.
