Whether you call it fernsehen, télévision, or television, RTL Group is probably involved. One of Europe's largest TV companies, RTL controls or has stakes in about 40 channels in 10 countries, including M6 (49%-owned) in France and its flagship RTL Television in Germany. The company is also a major producer of TV content through UK-based FremantleMedia, known for such programs as American Idol (and local versions in more than 50 countries), The Unteachables, and The X Factor. RTL also has an interest in more than 30 radio stations throughout Europe. Media conglomerate Bertelsmann owns about 90% of the company.
