Success is not Without Controversy

In 1909, when ADT was a subsidiary of Western Union, AT&T purchased the company. The federal government saw that the conglomerate was becoming a monopoly and in 1914 forced AT&T to change some things around. It ended up selling most of its Western Union holdings, which included ADT.

In the 1960s ADT grew large, but it had no structure. This brought on the attention of the Federal government again, which launched Monopoly proceedings. Part of the 1964 resolution was for ADT to develop a National Price list.
