Thank you. 02:04:22 Tom Trottier: Epilogue 02:04:35 Alan German (OPCUG Meeting Coordinator): My understanding is that STOP was used in telegrams between phrases but Morse Code didn't have a special code for this.

Was it before the teleprinter? 02:06:32 E O'Driscoll: What a great presentation. So very interesting! What a quick adjustment the public needed to make - similar to the rise in social media/AI these days. 02:06:56 Tom Trottier: "On printed telegram forms and in telegraph offices, a small dot for a period could be faint, misaligned, or lost entirely in transmission or printing, which risked changing the meaning of a message. Using the full word “STOP” made the end of a sentence obvious and much harder to overlook." 02:07:25 Michelle Faber: Very interesting and informative. Good evening. 02:07:39 Timothy: Very impressent presentation. 02:07:40 Tom Trottier: During World War I, governments and militaries leaned on STOP specifically to avoid any chance that a period might be missed or misplaced in critical orders; that convention then persisted into civilian telegram style long after. 02:08:09 Ed Morawski: REALLY great presentation! 02:08:23 Steve Parker: Cost and Transmission Factors Telegrams were charged by the word, and while the myth of punctuation costing extra persists, "STOP" became standard because it was a free four-letter word fitting billing units. Even after punctuation was added around 1937, "STOP" remained conventional in written and read-aloud telegrams 02:08:42 Allison: Really enjoyed the presentation.
