Radio broadcasting began in the US around 1920, and at the time of this picture radio listening was an exciting new high-tech pastime. Vacuum tube radio receivers (shown) which became available about that time could drive loudspeakers, allowing the whole family to listen together, unlike the previous crystal radios which required earphones so only one person could listen at a time. Early receivers used horn loudspeakers (shown) to get adequate volume from the low gain early tubes.
