Comparatively, in countries with less GDP, such as Portugal and Mexico the industry contribution is significantly lower. The US government spends more than other countries on military R&D, although the proportion has fallen from around 30% in the 1980s to under 20.[citation needed] Government funding for medical research amounts to approximately 36% in the U.S. The government funding proportion in certain industries is higher, and it dominates research in social science and humanities. Similarly, with some exceptions (e.g. biotechnology) government provides the bulk of the funds for basic scientific research.[citation needed] In commercial research and development, all but the most research-oriented corporations focus more heavily on near-term commercialization possibilities rather than "blue-sky" ideas or technologies (such as nuclear fusion).[2]
