From NIST’s Taking Measure Blog:
What technological application has had musical, timekeeping, navigational, scientific, traffic-control, emergency-response, and telephone applications?
Answer: WWV, one of the world’s oldest continuously operating radio stations.
NIST received the call letters WWV a century ago, in 1919. Since then, it has operated the station from several different locations — originally Washington, D.C., then a succession of locales in Maryland, and now Fort Collins, Colorado.
The programming is rather dry but very, very useful. WWV broadcasts time and frequency information 24 hours a day, seven days a week, to millions of listeners worldwide.
