In 1935—the height of the Great Depression—Ralph Allison founded ADC in the basement of his south Minneapolis home. He invented the audiometer, an electronic device to test hearing and ADC’s first product.

By 1942, the company designed a sophisticated audio system for the University of Minnesota. The resulting jacks, plugs, patch cords and jackfields became the cornerstones for ADC’s later entry into telecommunications.

In 1949, ADC sold its audiometer product line, and Ralph Allison left ADC to form a new company in California. ADC diversified and focused on transformers and filters for power lines, military electronics, telephone jacks and plugs.

In 1959, ADC entered into the coaxial product arena by developing high-frequency jacks and PBC-mounted transformers.

In 1961, ADC merged with Magnetic Controls Company, a manufacturer of power supplies and magnetic amplifiers with strong ties to the U.S. space program. The resulting company had a decade of mixed success. Although transformer sales boomed during the 1960s, other new product initiatives failed. The most significant product innovation during this period was the bantam jack, a miniaturized component that eventually became the standard for telephone circuit access and patching.

Building on its growing sales of jacks and plugs in the early 1970s, ADC introduced prewired, connectorized jackfields, wired assemblies, and test equipment for telephone operating companies. By 1974 the company was on solid ground, and by 1976, ADC was the largest independent supplier of test boards in the United States.

ADC’s growing presence as a supplier to the telecommunications industry was enhanced in 1983 when AT&T was ordered to deregulate by the federal government. By establishing the seven regional Bell operating companies (RBOCs) as independent entities, the U.S. market for telecommunications expanded by 90 percent. No longer

forced to purchase their equipment from the Western Electric Division of AT&T, the RBOCs began to look for suppliers like ADC that had a reputation for quality and innovation in the marketplace. Over time, the RBOCs became ADC’s key customer base.

To effectively focus resources on the emerging telecommunications market, ADC sold its magnetics business in 1984 and formally changed its name to ADC Telecommunications, capitalizing on the shift in technology from analog to digital. ADC became the industry leader in digital signal cross-connect devices and officially joined NASDAQ in 1984.

In 1995, all major ADC business units received International Organization for Standardization (ISO) 9001 certification.

In 1997, ADC celebrated $1 billion in revenue for four consecutive quarters.

In 2001, major restructuring and headcount reductions commenced in response to market crash for telecommunications products. ADC’s current world headquarters campus was also completed in this year.

In March 2004, ADC purchased the KRONE Group, a leading global supplier of copper- and fiber-based connectivity solutions and cabling products used in public access and enterprise networks.

ADC bought Fiber Optic Network Solutions (FONS) Corp. in August 2005, establishing the company as a leader in FTTX network equipment. The company then grew its fiber business to quickly support Verizon’s FiOS network build out, a large fiber-to-the-home deployment.

ADC launched its low-cost manufacturing operations in Brno, Czech Republic, and inaugurated its new Bangalore, India facility in 2006.

In 2007, the company acquired LGC Wireless, making ADC the world’s leading supplier of in-building wireless coverage and capacity solutions. This acquisition is followed by the

purchase of Century Man Communication in China in early 2008, bolstering ADC’s international sales and providing the company with the ability to support the build out of fiber networks in the world’s fastest-growing regions.

In 2009, ADC refined its business plan in response to rapidly-evolving market conditions in addition to adopting a new fiscal year-end change from October 31 to September 30. Revised plan included restructuring through much of the Americas, Europe, Middle East, and Africa regions.

ADC marks 75 years of business in August 2010, emerging from the global recession in strong financial and strategic positions. The company is aligned with the telecommunications industry’s most prominent trends, including the continued migration to FTTX networks, mobile broadband proliferation and enterprise investments in next generation data centers.
