How come CPB and PBS do not go private? Can't Bloomberg buy them or something?

2. They ARE largely private, most of funds anyway.

The Corporation for Public Broadcasting (CPB) is a private, nonprofit corporation created by the Public Broadcasting Act of 1967.
It serves as a steward of the federal government's investment in public broadcasting, acting as a buffer between partisan politics and public media, and providing funding for programming, stations, and technology.

The corporation doesn't produce programming and it doesn't own, operate or control any public broadcasting stations. The corporation, PBS, NPR are independent of each other as are local public television and radio stations.
