Creative industries provide services and products that are very important for the present society. Yet these industries, especially art, are often unjustly seen as an unimportant part of the economy. To prove the opposite, this paper uses the input-output analysis on selected sectors of creative industries in the Czech Republic to show their economic importance. The input-output analysis is based on relations between individual industries and can calculate general contribution of individual industry to the whole economy. At first, the paper introduces the term of creative industries, then the concept of input-output analysis and its utilization. After that, the input-output analysis is used on selected sectors of creative industries and the results are compared to other, "uncreative" industries. The results show the potential of creative industries and justifies that they are the integral part of the economy.
