"ProSieben on 7" is a thing of the past, and the balanced findability of public value content seems to be in danger on the device side. How can a fair co-existence of moving image sources be ensured? Does media policy need to intervene to regulate even before the big screen? A discussion about gatekeeping with remote control in hand.
