NordMende (full name: Norddeutsche Mende Rundfunk KG) existed from 1947 until 1977, when it was swallowed up by Thomson (which is also now the owner of the RCA and GE brands of consumer electronics). It was the descendant of one of Germany's oldest radio makers, simply called Mende, originally founded in 1923 in Dresden and named after its founder Hermann Mende. Mende existed until the end of WWII, when the Soviets seized whatever they could of the original Mende works. That reopened in 1948 under Soviet/East German control as VEB Funkwerk Dresden and existed as such until the reunification in 1989....

Hermann Mende's nephew Martin had been part of the Mende management since 1925. After the war and the Soviet seizure of the original Mende works, Martin Mende fled west to Bremen and in 1947 started a new radio company as a collaboration with one Hermann Weber. Because the East German regime would object to his using the name 'Mende' as a trademark, he simply added the 'Nord' ('North') prefix to it and it became 'NordMende'. By 1950 the company was able to move into a former Focke-Wulf aircraft factory in the Bremen area and set up a full-blown production line, and eventually built a full range of consumer electronic products (radios, tape recorders, and eventually televisions).

By the end of the 1950s, the transistor became widely available, and they dived right into production of transistor radios (and produced some very good ones). They continued producing radios, TVs, etc., until 1978, after which time Thomson had completely taken over production. Thomson continued producing products under the NordMende name into the 1980s and perhaps beyond, but that name is gone now...
