I have heard that small cable companies pay upwards of $11 per month per sub in retran fees. This article from the industry says..."According to Kagan, the average retrans fee charged by a broadcast station will reach $2.93 by 2022, putting it behind only ESPN ($11.08) and cable channel TNT ($3.09)." [1]

This increase by YTTV is driven by the leverage that ViacomCBS has because of the CBS locals then own. They are forcing YTTV to take these network. Until retransmission consent is changed, we are stuck paying the local station holders despite the fact that their content is free OTA.
