1940/50s

During World War Two Breville's focus turned to the war effort manufacturing mine detectors. In the war years Bill O’Brien also founded a special training scheme for air force radio operators. Despite the back-breaking effort of the war years Bill O’Brien later reflected that he was always proud of the contribution that Breville made to the war effort.

Post-war, the radio market boomed, but television was already flourishing overseas. Sensing the change, O'Brien realised that TV manufacturing would be a hard-fought battle between multinationals with limited survivors. He decided to focus on small appliances, selling the Breville Radio brand to the owners of Astor in 1951.
The same year, Bill's son John, 22, was on a working holiday in London when his father wrote: 'I've sold the radio business… here's a couple of hundred quid - give up your job and see what agencies you can pick up.' Before long Breville was handling a wide range of appliance brands such as Braun, Clairol, Pifco and Friedland.

The company also designed and manufactured a number of appliances that were ahead of their time: among its products was the “Breville Five Minute Washer”, which enjoyed spectacular success before and after the war.
