EI Niš, short for Electronic Industry Niš (Elektronska industrija Niš) is a company with headquarters in Niš, Serbia. It originated in 1948 from the foundation of the Institute for the Production of Radio Sets and Roentgen Machines, "RR Niš." In 1970-s and 1980-s it was one of the greatest Yugoslavian companies employing over 10 thousand people.[2] However, during the 1990-s most of the company business collapsed, due to lack of investing in research and sanctions the country was facing.
