Foreign competition, especially from Japan, caused perhaps the
greatest problems for Silicon Valley.
Silicon Valley had begun to worry about Japanese competition by the late 1970s. In 1981,
U.S. companies controlled 51.4 percent of the world's semiconductor market; Japan's share
was 35.5 percent.
Within seven years the figures had virtually reversed themselves, with Japan at 51 percent
and the United States 36.5 percent.
