Cross-media concentration is based on the audience shares of top 4 media groups in the sector. Audience shares of these groups are then weighted according to the relevance of media types in the country. The relevance of media types was calculated based on the most recent research carried out by DataWise 2017. According to this research, 73% of the population watch TV (at least one hour per day), 39% read daily newspapers (at least 1 newspaper per week) and 10% listen to the radio (at least one hour per day).
The top four owners of media in Turkey share 71% of the cross-media audience in the country.They have investments in at least three media types out of the four types studied throughout this research, which are radio, TV, newspapers and online web portals. Among the top media owners, Turkuvaz / Kalyon Group (30%) have investments in all four sectors. The second one is Ciner Group (15%) which has investments in only TV and online market after the Group closed its print version (Habertürk) in 2018. Although Demirören Group has investments in all four sectors, as the Group does not publicize the audience shares of its online news portals, MoM Turkey couldn’t count it to calculate the impact on the audience shares. Despite having no audience share data for its online news portal, Demirören Group (15%) became the third larger company in Turkey. The Doğuş Group is the fourth with the %11 of the audience share.
They are followed by Estetik Yayıncılık (Sözcü Daily and website - 10), Hayat Görsel Yayıncılık (Kanal 7, Radyo 7, haber7.com - 10%),State owned TRT (9%) and Türk Medya (5%)

The distribution data of print media in Turkey is an issue of large debate.

These are Demirören (23%), Kalyon Group (Turkuvaz) (15%), Türk Medya Group (12%) and Estetik Media (10%).
