OBJECTIVE: To analyze the content of television food advertising on Brazilian 'free-to-air' broadcast stations during children's programming. METHODS: This is a descriptive study which evaluated the content of food advertising between 08:00 a.m. and 06:00 p.m. on three Brazilian 'free-to-air' broadcast stations (A, B and C). Data collection was performed during 10 week days and weekends. Food advertising was organized according to the food group classification from the Food Guide for the Brazilian Population. The annual exposure to food advertising was obtained considering the national children average exposure to television of five daily hours. The χ2 and Fisher's exact test were conducted in order to identify differences in the content of television advertising in the morning and in the afternoon and between broadcast stations. RESULTS: One hundred and twenty six hours of programming were recorded, totalizing 1,369 commercials - 13.8% of food. There was major participation of 'sugars and sweets' (48.1%) and 'oils and fats' (29.1%) among food advertising and much food publicity in the afternoon (15.7%; morning: 12.2%, p = 0.037). Moreover, the broadcast with more audience was the one that advertised more food (A: 63.5%; B: 12.2%; C: 24.3%), especially 'sugar and sweets' (A: 59.2%; B: 43.5%; C: 21.7%). Finally, an annual average exposure to 2,735.5 commercials was obtained for Brazilian children, totalizing 2,106.3 of food rich in sugar and fat publicity. CONCLUSION: Food advertising is focused on poor nutritionally food, emphasizing the need for specific intervention strategies.

The Polish Radio began its activity on the first of February 1925. On this day the first program of the Polish Radio technical Society was broadcasted. From then on, the radio accompanied Polish people in good and bad times. The years 1946 – 1956 were not so glorious. At that time, Polish radio became the propaganda tool for the PPR and from December 1949 the PZPR. These parties, mainly under the slogans of the reconstruction of the country from war damage and the struggle for peace, sought to Stalinize Poland on the model of the USSR. While studying those times, it should be stated that information and publication hardly existed because it was replaced by a hypocritical, brutal and intrusive propaganda. However, history of Polish Radio in those years should not only been described in critical way. At that time, many very important and socially necessary initiatives took place. Since the first year after regaining independence, more and more new broadcast stations have been launched in various regions of Poland. New programs were broad-casting more and more often, such as "Muzyka i Aktualności", in which various mes-sages were given with ease, interwoven with modern jazz music.
