Is The FM tuner obsolete?

Over the air broadcast will always be around in some form.

With that in mind, demand will dictate how the market survives.

Sound quality of streaming is still evolving, but the same tune on the best tube  tuners still sounds more convincing. 

I'll take a Marantz 10B or REL Precedent over a nice streaming setup.

My Mac MR71 gets daily use.

I don't know. Predicting is hard. Especially about the future.

Meanwhile, CBS is selling off all their radio stations.
