"The amount of money Liberty Global spend on linear channel carriage will decline and shift to online rights, digital rights, On Demand rights, and SVOD rights."
This is clearly the trend and I can't see that stopping any time soon. It probably also explains why we aren't getting many new TV channels on Virgin Media these days.
