The graph shows federal expenditures as a percentage of GDP growing rapidly in the mid 1960s and leveling off only to rise again in the mid 1980s. Since then, U.S. technology R&D spending as a percentage of GDP has been overall declining or flat. Private industry funding since the mid 1960s has grown steadily, making up about two-thirds of U.S. R&D spending
