When was 9-1-1 started?

9-1-1, usually pronounced Nine-One-One (unlike nine-eleven which is pronunciation for the terror strikes), was introduced some time around the middle seventies; maybe around l97l. It was to be used for police and fire-emergency calls of the highest priority. Similar to SOS with Marine radio in non-vital emergency cases, such as abandoned cars, and vandalism.

To stop a crime or save a life dial 9-1-1, but it is preferred that you use your local precinct number for things like auto theft, and vandalism (keeping the 9-1-1 lines open for emergency duties!)
