How was the Corporation for Public Broadcasting (CPB) structured to avoid becoming a centralized federal broadcaster?

The Corporation for Public Broadcasting (CPB) was structured to avoid becoming a centralized federal broadcaster primarily by being insulated by a board. This board was designed to operate independently from the federal government, allowing for the decentralization of broadcasting authority. By establishing a governing body that includes diverse members, the CPB ensures that local stations maintain a level of autonomy in their programming and operations. This independence is crucial for avoiding government control over content, thereby promoting a wide variety of local voices and perspectives rather than a singular, homogenized federal broadcasting approach.

The other options do not reflect the CPB’s structure effectively. Direct federal funding does not necessarily prevent centralization; local content limitations or requiring viewer subscriptions would not inherently create the necessary oversight and independence from federal influence. The board's establishment and governance are key to the CPB's mission to support local broadcasting without direct federal oversight.
