Broadcast. CBS has acquired the remaining 50% stake in the cable network Pop held by Lions Gate Entertainment Corp., giving it complete ownership of the channel. The network, which airs series like “Schitt’s Creek,” had previously been a 50-50 venture between the two companies. Terms of the deal weren’t disclosed. CBS acquired its initial 50% stake in the channel for $100m in 2013 when it was known as the TV Guide Network. Since that purchase, the channel’s ratings among key demographics have declined and its national reach has fallen by 15%.
