Or the cable/internet provider will come out with their own streaming service. Such as Comcast Streampix announced a couple days ago, for only $5 per month.
Of course it's not available if you just have the internet plan...so add $15-20 to that...
Though if you're like me, you figured out that it's cheaper to have both TV and internet than just internet if you need useable speeds. Because their base internet plan with no TV is something stupid like 5Mbps(on a good day). To upgrade the 5Mbps plan to 20Mbps costs MORE than just switching to the TV/Internet plan, which comes with the 20Mbps plan.
They'll get their money one way or another.
