Not just cable
Video pie in general as a stand alone product is shrinking. Folks are re-evaluating if the value is there. Premium channels are getting hammered since there usually added cost. Housing market is dead so no increase in the amount of people ordering news video services. Generation of college kids with no inclination to get video from dish or cable spells trouble for video providers.
You'll soon see that the opposite will start to happen from last couple of years with double digit percentage increases in internet services and video services staying flat.
