Answer: People couldn't find the radio stations.
Explanation:
Every radio station is assigned a frequency on which they are to broadcast. These frequencies identify the radio stations such that people are able to find them by just going to that frequency.
This was the main reason why the government had to assign radio frequencies. Initially, radio stations took on different frequencies and finding them could be cumbersome as they sometimes changed. By assigning one frequency to a station, listeners could always find it there.
