Prior to 1930 Philips imported radios such as the model 2510 but they commenced local manufacture in 1931 following the increase in import tariffs. Only two models were produced and production was soon halted. It wasn't until 1934 that production restarted and Philips grew to become one of Australia's largest electronics manufacturers. They also made radios sold under the Briton, Mullard and Fleetwood brand names. Television production started in 1956 and continued until the 1980s. They also manufactured valves, television picture tubes and transistors.
