The producers of consumer goods control to a great extent the information we receive. Because broadcasters and publishers are largely dependent for their revenue on the advertising paid for by these producers, they will refuse to broadcast or publish advertising which is in opposition to that of their major sponsors. This form of censorship is dictated by the commercial interests; the interests of consumers are ignored.
Television networks refuse to broadcast the advertisements of The Media Foundation for "Buy Nothing Day" and "TV Turn-Off Week", saying these advertisements are inimical to their business interests.
