PBS has applied its "conflict of interest" guidelines to refuse programming that receives sponsorship from unions, lesbians or battered women, on grounds that these groups have a "vested interest in the subject matter of the program." When it comes to corporations, however, the network follows a different standard. Currently the network is premiering a six-hour series about the global economy which was sponsored by major corporations that have a clear interest in the show's content. Titled "Commanding Heights: The Battle for the World Economy," the series has already received a rave review from the Wall Street Journal under the headline "PBS Likes Capitalism More Than the Commercial Networks Do," in which it hailed the series as a "paean to private enterprise."
