As the worst of the depression passed and the deportations and "voluntary" departures diminished, the rhythm of life in the barrio resumed, presenting a fascinating picture of a community suspended between two cultures. Radios covered with colorful serapes broadcast both the latest popular songs and native folk melodies of Mexico, called rancheros.

I'd like to know how radios can broadcast songs.
Thank you in advance for your help.

    To broadcast means to distribute without request or action on the part of the recipient. In the case of a radio, or indeed any music playing device such as an MP3 player with speakers, the songs are broadcast to anyone who is within hearing range.

    From the WRF dictionary:

    • to cast or scatter abroad over an area, as seed in sowing.
    • to spread widely; disseminate: She broadcast the good news all over town.

    The idea is that the sound from the radio (or the signal from the transmitter) goes in every direction - like the light from a light bulb, rather than that from a flashlight.
