IGB Eletrônica S.A. (Portuguese for IGB Electronics), doing business as Gradiente, is a Brazilian consumer electronics company based in Manaus, and with offices in São Paulo. The company designs and markets many product lines, including video (e.g. televisions, dvd players), audio, home theater, high-end acoustics, office and mobile stereo, wireless, mobile/smartphones, and tablets for the Brazilian market. The company was founded in 1964. In 1993 they founded Playtronic, a fully owned subsidiary that licensed the manufacturing of Nintendo consoles in Brazil, and while publishing games for various systems they also provided Portuguese translations of some games (among them, South Park and Shadow Man for the Nintendo 64). However, they stopped the partnership with Nintendo in 2003 because of the high price of the dollar at the time.
