The purpose of this work is to investigate the perceptions of parents about advertising of food to children on television. The theoretical research includes a review of marketing to children, the analysis of influential factors, the influence of food advertising aimed at children, the perceptions of the parents and the issue of regulation of this area of advertising. The empirical research conducted via a questionnaire to the parents does not confirm the connection between the time spent in front of the television and the behaviour of children, but it does indicate at the negative attitudes of parents about advertising of food that influence their moderately restrictive attitude on the prohibition of such advertising.
