Early radio was like the internet

Have a look at some early shows that were on radio:

As you can see there is a show about stamp collecting, there's another show called 'Commuter's Clock' (I'm assuming this simply TOLD THE TIME OF THE DAY since it was broadcast early the morning) and there's another show, called 'Dental Clinic' which could about about dental hygiene.

At any rate, very early radio was all about a variety of subjects.  I look at it a bit like the internet.
