Every year 549.5 million smart home devices are expected to be delivered worldwide. This corresponds to a growth of 26.8 percent compared to the previous year, according to figures from IDC market researchers. Especially in the market for intelligent assistants, the competition is getting tougher. Today, we are taking a closer look at how sales figures are developing, which smart assistants are popular and whether Amazon, Google or Apple will dominate.

The two dominant categories in this area are Smart Speakers and video entertainment products. They will account for 71 percent of the market this year and will have an annual growth rate of 12 percent through 2022, according to IDC's Worldwide Quarterly Smart Home Device Tracker. The video entertainment segment, i.e. primarily smart TVs and digital media adapters, will account for the largest share of the smart home market. IDC also expects strong growth in the area of intelligent home surveillance and smart security solutions.
