The Indian electronics industry saw growth in the early years of the 21st century, encouraged both by government policies and incentives and by international investment. Its key and most resource-intensive segment, the semiconductor industry benefitted from domestic demand growing briskly. Semiconductors were required by a large number of industries, including telecommunications, information technology, industrial machinery and automation, medical electronics, automobile, engineering, power and solar photovoltaic, defense and aerospace, consumer electronics, and appliances. As of 2015, however, the skill gap in the Indian industry threatened progress, with 65 to 70 percent of the market relying on imports.
