Modern campaign finance law stems from the Federal Election Campaign Act (FECA), first enacted in 1971 and amended in 1974, 1976, and 1979. FECA mandated reporting requirements similar to those in place today, such as quarterly disclosure of a political committee’s contributions and spending. FECA also limited spending on media advertisements, though that restriction was later declared unconstitutional. The law provided a framework for the creation of political action committees.
