When it comes to the number of connected devices, the counts are consistently into the billions.
One forecast not long ago pegged the number of connected devices this year already at 12 billion.
That projection, by Frost & Sullivan, said the number of connected devices would grow to more than 45 billion by 2023, at an annual growth rate of 20%.
Now a new forecast says the number of connected devices globally this year will reach 20 billion, with another 10 billion added over the next four years.
One of the main drivers of growth is the smart home, according to the forecast by Strategy Analytics.
By 2020, the number of connected devices will total around 50 billion, according to the forecast.
Interestingly, smart home devices will overtake smartphones by 2021 as a share of connected IoT devices.
However, the rate of growth is another issue.
While the Internet of Things will grow by 17% this year, annual growth rate will decline to 9% by 2021, according to the research firm.
For context of the scale of the Internet of Things, the personal computer, the original connected device, now represents only 5% of the total market.
