Until the 1920s, radios weren’t that easy to use. 

Adjustable or interchangeable coils were needed to tune them. 

Before then, radios had mainly been used in the shipping industry and by the armed forces.

More and more consumers wanted a radio set at home, so these needed to be easy to use.

These radio sets only had a few knobs.

The radio revolution was driven by the radio tube, which amplifies radio signals.

Radios were fitted with loudspeakers, so the whole family could listen to a broadcast together.

In the 1930s radio became a real mass medium.

Radio tubes produce heat, so they needed to be enclosed in radio cabinets. The manufacturers produced radio sets with beautiful wooden cabinets, which fit perfectly into the home’s interior decor.

For many people, a new radio set was extremely expensive. 

It was also a status symbol. To emphasize this, manufacturers hired designers to create beautiful radio cabinets.

To protect the cardboard speaker, manufacturers fitted decorative features in front of it.

Like these waves and stars – which are made of Bakelite (an early type of plastic) – on a 1931 radio set. A few years later, this became Philips’ official logo.

The newly introduced transistor did not produce much heat, so 1950s radio sets were much more energy efficient.

Small, portable battery-powered radio sets became available.

In the second half of the twentieth century, radio sets were increasingly made of plastic and other materials. They were shaped by numerous design trends.

By that time, radios were everywhere. Small and affordable, these were no longer seen as status symbols.

As a result, radio cabinets gradually disappeared from people’s living rooms. This model dates from the 1970s.
