It was the third-largest shopping mall in the world at the time of its opening but has since been surpassed by much larger malls. The mall was originally developed and owned by Edward J. DeBartolo Corporation. A 1996 merger between the mall's developer, now known as the DeBartolo Realty Corporation, and Simon Property Group brought Century III Mall under the Simon DeBartolo Group heading, who owned the mall until 2011. The vacant mall site is currently owned by Las Vegas-based Moonbeam Capital Investments LLC.
