"Tungsram located in Hungary is known for their light bulbs and electronics. Established in Újpest (today part of Budapest, Hungary) in 1896, it initially produced telephones, wires and switchboards. The name "Tungsram" is a portmanteau of "tungsten" /ˈtʌŋstən/ and "wolfram" /ˈwʊlfrəm/ (the two common names of the metal used for making light bulb filaments).
Before the nationalization of the Communist Government in 1945, the company was the world's third largest manufacturer of light bulbs and radiotubes, after the American General Electric and RCA companies." - (en.wikipedia.org 11.08.2021)
