Just take a gander at the factory shipment numbers for 2015, courtesy of the Association of Home Appliance Manufacturers (AHAM).

Total wholesale sales were up an impressive 8.1 percent in unit volume, to some 72.5 million pieces, which certainly gave the CE industry a run for its money. This compares favorably to 2014’s appliance performance, when total industry shipments rose a more measured 4.9 percent.
Leading the appliance parade last year was the cooking category, up a whopping 15.2 percent on strength in microwave ovens — ahead 22.6 percent — and electric ovens, up 7.4 percent. Those gains helped offset a serious 32.3 percent drop in gas-oven shipments, which totaled just 20,000 units.
