One thing that is important was the way governments viewed Radio broadcast into homes. Some like the U.S. Radio stations were supported with ad revenue and was in the control of private hands. This had the effect that the radio programming was more geared to popular taste and allowed the broadcasting of sports which was very popular later on thier would be more genres that later became a blueprint of the genres on Television. Also during this time many inventors are trying different methods of broadcasting moving pictures, the start of Television, and by the 30’s we had broadcast Television yet it would no be till after WW2 that Television would really take off.
Now in some countries Brittain for example they were horrified by U.S. commercial broadcast and decided to take an approach of the government owning the stations and a tax would be levied on radio recievers. While from a cultural perspective the programming could be called high culture. Many Brits prefered radio Luxembourg becuase it was commercially operated and provided more entertainment geared toward common taste.
