Philips purchased a company named NSF in the 1920s which produced radios and transmitting equipment. NSF started to market their product in Germany using the brand name Aristona in the 1950s. The sales of Aristona turned out to be significantly better so Philips expanded the lineup and began marketing in other countries under this name. Typically Aristona products were very similar to Philips models at a lower price point.
