Each year since 1990, SDM has surveyed the largest security dealers operating in the United States, tabulated the results of these surveys, and ranked the firms from largest to smallest in a report called the SDM 100, published each May. In a $29.5 billion industry (based on SDM’s January 2007 Forecast Study), these largest 100 firms captured $6.95 billion in total revenue – about 24 percent market share – and counted 11.3 million subscribers (customers) in the most recently reported year.
