From 1 April 2007, Swiss control is no longer a condition for obtaining a concession for the diffusion of radio and television programmes. Since then, a concession for the diffusion of radio and television programmes can only be granted  to companies having their headquarters in Switzerland. Concessions to foreign-controlled companies may be refused if reciprocity is not accorded.

c. demonstrates to the licensing authority the identity of the majority holder of its capital and who makes substantial financial resources available to it; [...]

2 In the absence of any international obligations to the contrary, a legal person controlled from abroad, a domestic legal person with foreign participation or a natural person without Swiss citizenship may be refused the licence if the corresponding foreign state does not guarantee reciprocal rights to a similar extent.
