In addition to overseeing the ESRB, the ESA organizes the Electronic Entertainment Expo (E3). After the IDSA's formation, the video game industry had become concerned over the treatment they had received at recent Consumer Electronic Shows and were seeking another trade show venue. The IDSA partnered with International Data Group (IDG) to organize the first E3, held in May 1995 in Los Angeles. The first E3 proved more successful than originally expected, and the IDSA negotiated with the IDG to take ownership of E3 and its intellectual property, with the IDG serving to help handle execution of the event. In a 1997 interview, IDSA president Doug Lowenstein said E3 is also the primary source of income for the IDSA.
