According to publisher notes, The ADT Transmitter was, “A monthly news-magazine of outstanding events and features concerning fire, burglary and holdup . . . edited and distributed for the information of employees, subscribers and other interested persons.” The ADT Transmitter was published monthly from 1929 to 1970.

Most issues of The ADT Transmitter are 8 pages in length and printed on standard 8-1/2 x 11 inch paper. Typical layout is 3 columns per page, with pictures interspersed throughout each issue.

The ADT Transmitter was printed in two slightly different formats. Early issues from 1929 to 1936 were newspaper-like in format and printed in a single color (black).

Beginning in 1937 the format became more magazine-like, with a tri-color (red, black and white) title across the upper two inches of the front page, and a black and white photo filling the remainder of the page. Remaining pages were mostly mono-color (black). Most pages included a photo or two.

With the change in format, content also changed. Issues from 1929 to 1936 highlighted primarily internal organizational activities, such as captures, promotions, etc. The format revision in 1937 altered content, by providing more focus on the customer. Most articles included subscriber names and reported fires, burglaries, holdups and other events where ADT services were involved.

With the format revision in 1937, editorial content was also expanded, providing a forum to discuss topics of interest in loss prevention and the merits of ADT protection.

Beginning in 1960, the front page was redesigned slightly, by giving the title a more modern looking format. Content was also modernized on other pages with the addition of a third color (typically red or blue) to highlight section titles and borders.

A number of ADT Transmitter issues have been scanned and uploaded to this web site. Also, an index of subscriber names and ADT Associate names appearing in the newsletters has be created. Details for viewing and/or downloading the files are on the ADT Transmitter Archives page.
