exploit the technology . gold and stock also developed a messenger system that sent instructions to and from the stock exchange floor . three years later the president of gold and stock telegraph company woke up to a burglar in his home which inspired him to create a telegraph based alert system . this system eventually connected 50 of his neighbors to a central station where all the alert boxes were monitored . 8 there were many small telegraph delivery companies in the united states in the 19th century . in 1874 57 district telegraph delivery companies affiliated and became american district telegraph . with the increase in telephone usage in the late 19th century adt s messenger business slowly declined in popularity . adt tried branching out and developing their signaling

at that time . in 1909 western union and adt came under the control of american telephone & telegraph company at & t . adt began to expand into new areas such as fire alarms and security alarms

was shown to provide almost 80 % of the central station alarm service in the united states . in some cities such as new york city and memphis tennessee they were the sole provider . they were also found to have forced competitors out of business by lowering prices below cost . they would charge national accounts very low prices in cities with competitors and much higher prices where no competition was available . adt was forced to adopt a national price list which could not be varied to help establish central station competitors in cities without competition and to pay fines and triple damages to the federal government customers and local competitors . 9 in the early part of 1987 the firm of hawley goodall owned by lord ashcroft bought the indianapolis based crime control inc. the fourth largest company in the u.s. security market for 50 million . later in the year it bought adt and moved to bermuda . this purchase transformed hawley into the leading security services business in the united states and resulted in the majority of its revenues coming from the north american market . as a result of the acquisition hawley changed its name to adt limited and decided to refocus its business around security services . at the end of 1987 the company sold its north american based facility services business to denmark s iss a s. in 1997 adt was purchased by tyco by means
