Question

What did the rapid development of mass media during the 1920s accomplish?

Answer 1

Most of mass media remained constant during the 1920s with the exception of radio, which had a rapid adaption curve.

At the time, the number of households gaining radios was seen as spectacular.

Initially radio stations were constructed to be rented out to users.  But some experiments indicated the best route was to build an audience base instead of renting studio time, and this soon led to linkage in the Associated Press sharing format and networks were created.   The resulting audience base changed advertising and commercials were introduced with great success.  

Instead of firms purchasing blocks of time or sponsoring programs, the stations produced the programs and sold short segments of air time to advertisers. This same business model was followed when television was introduced.

The introduction of radio was much like the early days of the Internet where people could not figure out how to make money from broadcasting.  

By the end of the 1920s the Federal Radio Commission was created (later the FCC) and unlike newspapers and magazines covered by the First Amendment, the federal government controlled broadcasting with the argument "the airwaves belong to all of us."

Some governments today are trying to impose regulations on the Internet using the same arguments fostered back in the 1920s during the rapid development of radio.

I hope this answer helps you.
