Telecommunications is also a key enabler of productivity across the U.S. economy and society.6
Not only is telecommunications an industry in itself, but it also benefits nearly every other industry. In the 1990s the U.S. GDP grew rapidly, and the U.S. economy was among the strongest in the world. It is widely believed that the Internet economy played a significant role in this success.
Today, however, new wireless applications, low-cost manufacturing innovations, and handset design are some of the areas in which the Asian countries are outinvesting the United States in R&D and are seeing resulting bottom-line impacts to their economies. For the United States to compete in the global marketplace—across industries—it needs the productivity that comes from enhancements in telecommunications. If the telecommunications infrastructure in the United States were to fall significantly behind that of the rest of the world, the global competitiveness of all other U.S. industries would be affected. Conversely, the growth in U.S. productivity has been based in part on a telecommunications infrastructure that is the most advanced in the world.
U.S. leadership in telecommunications did not come by accident—success at the physical, network, and applications levels was made possible by the U.S. investment in decades of research and the concomitant development of U.S. research leadership in communications-related areas. Telecommunications has been and likely will continue to be an important foundation for innovative new industries arising in the United States that use telecommunications as a primary technological enabler and foundation. Recent examples of innovative new businesses leveraging telecommunications include Yahoo!, Amazon, eBay, and Google.
