Some history of the name Norelco, from Wikipedia.
https://en.wikipedia.org/wiki/Norelco
From the early 1940s, Philco was legally able to prevent Philips from using the name "Philips" on any products marketed in the United States, because the two names were judged to sound similar and that it may cause litigation.[1] As a result, Philips instead used the name Norelco, an acronym for "North American Philips [electrical] Company".
