Great insight from the Wonderful World of Wiki

For communication scientist and media economist Manfred Knoche at the University of Salzburg, Austria, advertising isn’t just simply a ‘necessary evil’ but a ‘necessary elixir of life’ for the media business, the economy and capitalism as a whole. Advertising and mass media economic interests create ideology. Knoche describes advertising for products and brands as ‘the producer’s weapons in the competition for customers’ and trade advertising, e. g. by the automotive industry, as a means to collectively represent their interests against other groups, such as the train companies. In his view editorial articles and programmes in the media, promoting consumption in general, provide a ‘cost free’ service to producers and sponsoring for a ‘much used means of payment’ in advertising.^[30] Christopher Lasch argues that advertising leads to an overall increase in consumption in society; "Advertising serves not so much to advertise products as to promote consumption as a way of life."^[31]
