1874 - 1890

1874

Most people don’t like to talk about age, but we’re proud of ours! Just two years before the United States celebrated its first centennial, ADT was founded, not as a security company, but as a telegraph company. Surprising – we know! The American District Telegraph Company was in the business of providing a great service to its customers, just as it is nearly 140 years later as ADT.

Before leading the way in the electronic security industry and moving headquarters to Florida, we began in Baltimore, MD, embracing the most advanced communications technology of the 1800s. While they didn’t have instant messaging back then, they had something similar. A telegraph system! This form of communication was more popular than carrier pigeons in the 1870s because it was faster and more reliable. A hand-written message was provided to a telegraph company from the sender. These messages were transmitted over telegraph lines to a receiving telegraph company at another location. They then decoded, transcribed, and hand delivered the message to the recipient.

1891 - 1909

Late 1800

As a telegraph company, we meant business, and the ADT Messenger Boys were proof of this. Promptness, diligence, and speed were important. In cities across the country, ADT Messengers could be seen running from building to building, relaying customers’ messages. “Running” being the key word – they were allowed no more than 1.5 minutes per street block and less than 2 minutes in a customer’s building!

Early 1900s

We pride ourselves on being able to offer you ADT 24 Hour Alarm Monitoring Service – countrywide we have eight Customer Monitoring Centers (CMC) with 3,000+ employees keeping guard 24/7. Our first CMC came in the form of watchmen’s signal timers which were monitored in an ADT central office. We were just doing what we do best – making sure the people and things you value most are safe.

1902

Did you know ADT’s first president was a colonel in the United States military? With humble beginnings serving as a messenger boy and working his way up to president of Western Union and ADT simultaneously, Colonel Robert C. Clowry led the company for eight years.

1909

ADT and Western Union came under the control of AT&T, thus beginning our transition to the signal business, which was the forerunner of ADT Security Services.

1920

With the invention of cars our telegraph services were “far more effective than before,” said a customer during the early years of the automobile. Our drivers had to be more alert though, making way for horses and avoiding dogs in the streets.

1940

We really got going in the 1940s when we pioneered progressive ADT-branded technological developments, such as the Teletherm automatic fire detection system, Telewave automatic intrusion system, and ultrasonic burglar alarm!

1969

1969 was a big year for us as we became a publically owned company. President at the time, Lawrence J. O’Brien, bought the first 100 shares of ADT stock on the New York Stock Exchange!

1970 - 1997

1974

Happy Birthday, ADT! We made it through the invention of the automobile, the sinking of Titanic, the Great Depression, silent films, two world wars, and Woodstock, making it to 100 years of protecting what matters most to our customers.

Late 1980s

The American District Telegraph name is no more. We were approved by our shareholders to change our corporate name to ADT Security Systems, Inc.

1981

The Safewatch residential system was introduced, leading into a solid decade of product announcements, including ADT Focus, a security technology for commercial applications; Unimode fire system; and CentreScan, a computer-based proprietary security system.

1994

We thought we reached a milestone in 1974, but this year may have topped that. We added more than 180,000 new residential systems and surpassed one million customers!

1997

ADT was purchased by Tyco International.

2001 - 2011

2001

Talk about staying ahead of the times – we were the first security company to offer a Web-enabled home security system, ADT Safewatch iCenter!

2004

Welcome ADT Companion Services’ new system! It was understood that people were living longer than ever before, and we wanted to make sure they could live comfortably and safely in their homes for as long as possible.

2010

Have a smartphone? We know you do! That’s why we launched ADT Pulse® Interactive Solutions in 2010. ADT Pulse makes it possible for people with any compatible smartphone or laptop to remotely access and control not only a home security system, but several applications including lighting, climate control, small appliances and much more, all in real-time.

2011

ADT’s parent company, Tyco International, announces that its Board of Directors has unanimously approved a plan to separate the company into three independent, publicly traded companies. The standalone ADT North America residential business will be the leading provider of security and fire alarm systems in North America, serving more than 6 million residential homes and small businesses.

2012 - Present

2012

ADT completes its separation, preparing to spinoff from Tyco International. ADT starts the new fiscal year by debuting as an independent public company and begins trading on the New York Stock Exchange (NYSE: ADT).

2016

ADT enhances its customer service experience and product portfolio by merging with Protection 1 under the leadership of CEO Timothy J. Whall. The combined company serves 8 million customers through its 18,000 employees in nearly 200 locations throughout the US and Canada.
