Electric Shavers Norelco
From the early 1940s, Philco was legally able to prevent Philips from using the name "Philips" on any products marketed in the USA, because the two names were judged to sound similar and that it may cause litigation. As a result, Philips instead used the name Norelco, an acronym for "North American Philips [electrical] Company." Philips continued to use that name for all their US products until 1974, when Philips purchased The Magnavox Company. Philips then relabeled their US consumer electronics products to the Magnavox name, but retained the Norelco name for their other US products. When Philips bought Philco in 1981, Philips was able to freely use the Philips name for all of their US products.
