It began in 2012 as a concert at the Verizon Wireless Amphitheatre in Irvine, then moved to the Los Angeles Memorial Sports Arena for two years with additional events. This year, July 31-Aug. 2, KCON is taking over the Los Angeles Convention Center with performances, panels, workshops, meet-and-greets, shopping and food, as well two nights of concerts at Staples Center next door.
