A company named “Ideal” was first founded in Berlin when radio was still in its infancy. Every unit was carefully tested by technicians and labeled with a seal for quality – the blue dot. It did not take long before customers simply asked for the “bluepoint” (which means in German BLAUPUNKT) products. The blue dot quickly became a symbol of outstanding quality.
