Within the framework of the information and documents obtained in the sector inquiry conducted into advertisement services in accordance with the Competition Board (Board) decision dated 27.03.2025 and numbered 25-13/284-M, the Board took the decision dated 12.11.2026 and numbered 26-41/1148-M to launch an ex officio investigation to determine whether Fifty5Blue Medya Araştırmaları Danışmanlık ve Ticaret AŞ (FIFTY5BLUE), which provides television audience measurement services, violated the Act no 4054 on the Protection of Competition through its practices related to these services.

Television audience measurement results, commonly referred to as ratings, indicate how many people watch television channels and programs, as well as which audience groups they reach. Advertisers and media planning and buying agencies acting on their behalf use this data to determine the channels, programs and time slots in which their advertisements will be placed. The reliability and comparability of viewership data are important in enabling advertisers and agencies to accurately assess the costs of reaching their target audiences through different channels and allocate their advertising budgets accordingly. These data are of particular importance for television broadcasters as well, enabling them to accurately demonstrate to advertisers the audience they can reach, to substantiate this reach when negotiating over advertising rates, and to compete for a share of advertising budgets.

The investigation will assess the potential effects of practices relating to television audience measurement services on measurement results and on the competitive conditions in the television advertising market, examining whether FIFTY5BLUE has infringed the Act No. 4054 on the Protection of Competition when carrying out activities such as using the data that forms the basis of the measurement, establishing and managing the audience panel, processing viewing records and reporting measurement results.

Respectfully announced to the public.
