[What messages did the Norwegian tobacco industry communicate to consumers in its advertising?].
BACKGROUND
A Norwegian official report, NOU 2000: 16, Tort liability for the Norwegian tobacco industry, concludes that Norwegian law and judicial practice allows lawsuits against the tobacco industry for damages. A crucial claim in such suits would be that the industry withheld information on health risks and addiction and instead used advertising messages that undermined the information campaigns initiated after the reports on smoking and health from the U.S. Surgeon-General and the Norwegian Board of Health in 1964. This article reports a study of differences in tobacco advertising in Norway before and after 1964.


METHODS
A total of 1,945 photographs of advertisements in two popular weekly family magazines over the 1955 to 1975 period were stored in a database along with information on date of publication, size, copy and message, presumed target group, and characteristics of persons and situations shown.


RESULTS
Up until 1964, advertisement space per year in these magazines totalled 100 dm2 (11 sq. feet). The amount of advertising space then increased up until 1973, to 2,033 dm2 (219 sq. feet). The share featuring women went up from 33 in the 1955-64 period to 62% in 1965-75, when 51% of advertisements showed women smoking while 31% showed men smoking. Pre-1964 advertisements primarily contained information to smokers on price, type of tobacco, packaging and country of origin; after 1964 the advertisements developed a more universal appeal associating smoking with various social situations marked by style, well-being and comfort. The tobacco was said to be pure, fresh, mild and natural, and the filter was claimed to have protective properties.


CONCLUSIONS
It is probable that the cognitive dissonance created by more health information on smoking after 1964, i.e. the necessary motivation to quit, was reduced as a result of strategic changes in the amount and content of advertising.
