Congress limited CPB's discretion in spending the federal appropriation. The corporation's authorizing law imposes a budget allocation formula that divides the appropriation as indicated in the chart.
Dividing CPB funds between TV and radio had been a repeated struggle until 1981, when Congress imposed a peace-making formula proposed by Rep. Tim Wirth (D-Colo.), chair of the House authorizing subcommittee. The 75-25 percentage split between TV and radio was based on experience, though with public radio's later growth, it made radio stations more dependent on private-sector fundraising than public TV is.
Robben Fleming, then president of CPB, complained that the formula "emasculates" CPB, and his successors periodically have objected to the loss of discretion over spending.
Outside the formula, CPB has had periodic special appropriations to upgrade its satellite systems, separate Department of Education funding for Ready to Learn children's programming and major Annenberg Foundation donations for educational programs and services.
How the law lays out the formula
Excerpt from CPB's authorizing law: an update of the updated Public Broadcasting Act, boldface and colored boxes added:

CPB administrative costs

of the Corporation for fiscal year 1989, and for each succeeding fiscal year the amount which shall be available for such administrative expenses shall be the sum of the amount made available to the Corporation under this subclause for such expenses in the preceding fiscal year plus the greater of 4 percent of such amount or a percentage of such amount equal to the percentage change in the Consumer Price Index, except that none of the amounts allocated under subclauses (II), (III), and (IV) and clause (v) shall be used for any administrative expenses of the Corporation and not more than 5 percent
of all the amounts appropriated into the Fund available for allocation for any fiscal year shall be available for such administrative expenses
