The shopping hub, promoted as CHRISTOWN SPECTRUM MALL since November 2007, has gone through two official name changes over the years. It has also been renovated and demalled to such an extent that it is now totally unrecognizable from its original configuration. What few circa-1961 sections that remain are shown in black. Everything else was added between 1995 and 2007. 

The first phase of Phoenix's light rail system began revenue service in December 2008. The 19.7-route-mile Valley Metro starter line connected the southeast and north sections of the city. Its 19th Avenue / Montebello station was adjacent to CHRISTOWN SPECTRUM MALL.

By the 2020s, the shopping hub is promoted as simply CHRISTOWN SPECTRUM. In its present state, the complex covers around 1,200,000 leasable square feet, contains sixty-five tenant spaces and has parking accommodations for over 4,300 autos. CHRISTOWN lost two anchor stores in the fall of 2020, when Costco and J.C. Penney pulled up stakes. The Costco spot was eventually filled by American Furniture Warehouse.
