The purpose of this study was to conduct a comprehensive content analysis of television food advertising and provide data on current levels of food advertising in Australia. All three commercial stations available on free-to-air Australian television were concurrently videotaped between 7 a.m. and 9 p.m. on two weekdays and both weekend days in four locations across Australia to provide a total of 645 It for analysis. Each advertisement was categorized as 'non-food ad', 'healthy/core food ad' or 'unhealthy/non-core food ad' according to set criteria. Thirty-one percent of the advertisements analyzed were for food. Eighty-one percent of the food advertisements identified were for unhealthy/non-core foods. When comparing the results of this study with previous research, it was found that the number of unhealthy advertisements screened per hour had not changed over the past few years. On weekdays, the number of advertisements increased throughout the day to peak at more than five advertisements per hour in the 6 p.m.
