Some other recommendations include: a) maintaining minimum standards for public service programs for both private and public broadcasters; b) limiting ownership changes that are not in the "public interest"; c) creating regional broadcasting councils that will allow for greater public input in broadcasting; d) creating a new federal organization to license public service broadcast facilities for provinces wishing to engage in educational broadcasting; e) restructuring CBC finances to allow for a five year financing plan; f) ensuring that cable television is treated as part of the national broadcast system; and g) the creation of two separate boards to regulate private and public broadcasters.
