Lots of people still have land lines. But cell service has been around for a generation and land lines still exist. Im not sure thats the best example. In the US where the cable companies are part of massive media conglomerates, you begin to see this already where they get streaming options as part of cable packages. Bell sort of does this with Crave. I think the big Canadian companies will become mostly internet...everything will be internet. And everything will be streaming but there are lots of streaming options that dont have great aps or dedicated aps on every platform where a cable company can act as a gateway, like Amazon does.
Either way, its fascinating.
