This master's thesis focuses on how the Czech Television covered the one hundredth anniversary of the founding of Czechoslovakia in its main evening news program. It was an important theme of the whole year 2018, it wasn't the only anniversary we commemorated in that year, though. In 2018, eighty years have passed since the signing of the Munich Agreement in 1938 and seventy years since the 1948 Czechoslovak coup d'état. It's also been fifty years since the Prague Spring and the Warsaw Pact invasion of Czechoslovakia in 1968. Last but not least, we celebrated twenty-five years since the founding of the Czech Republic in 1993. All these events are significant milestones in Czech and world history of the twentieth century. Therefore, the thesis analyzes to what extent Czech Television dealt with these events. The aim of the thesis is to get an insight into the coverage of this topic throughout the year 2018 and to find out how much space was provided for each anniversary and what the nature of the posts was.
