The Long-Range Financing Task Force of the Corporation for Public Broadcasting estimates that a capital investment of $534 million will be necessary to provide public broadcasting coverage to 90 percent of the population. This assumes that the federal share of capital expenses will be nearly 50%. Operating costs for a fully developed system will require $475 million annually with the federal government contributing $166 to $237.5 million of that. The system, under this funding arrangement, would include state and regional networks, the national libraries, station-affiliated and independent producers, and experimental centers. In order to reach these estimates the Task Force recommends adhering to 12 principles which review the balance of federal and non-federal funding, the long-range planning, and the necessity of underwriting the system. The success of the existing funding plans anticipates partial reliance on general tax revenue, sales from satellite systems, and an implementation of matching-funds systems. (MC)
