ADT monitoring: Protecting America for more than a century

ADT began in 1874 as a cooperative among 57 district telegraph companies. The company, known as American District Telegraph, expanded its business services when popular use of the telegraph declined in the late 19th century.Its signaling technology would lay the foundation for America's first monitored burglary and fire alarms. The company ceased to provide telegraph services shortly after the turn of the century. Even so, it was and is still known as ADT, an abbreviation of the original telegraph cooperative.

ADT didn't reach the 1 million customer milestone until the 1990s. But after America's homeowners started recognizing the benefits of 24-hour remote security monitoring, the popularity of home security systems increased rapidly. Over the next 20 years, ADT expanded its customer base six-fold and now serves homes and businesses in every corner of the country.
