Is the Internet of Things Really Happening?

Over the last few years there has been much speculation about the inevitable growth of the Internet of Things (or Internet of Everything). Forecasts have suggested anywhere from 30 to 50 billion devices will be connected by 2020. Cisco has estimated that the global IoT ecosystem will have a value of $14.4 trillion by 2022, and IDC has projected yearly IoT market revenue to increase to $1.7 trillion by 2020.

Here we are now in 2016, a few years into the future they were talking about back then, and it may be a good time to take a look the current state of the IoT and see how it measures up to all of these lofty expectations. Are people really embracing IoT technology at this rate? Is this money really being invested?


Connected Devices

First, let’s take a look at the number of connected devices. If we flash back to 2013, we find that Gartner released a report entitled “Forecast: The Internet of Things, Worldwide, 2013”. In this report, they predicted that the IoT will include 26 billion connected devices by 2020. Two years later, Gartner reported a total of 4.9 billion connected devices at the end of 2015, up from 3.8 billion in 2014. Gartner also revised their 2020 estimate, anticipating 20.7 billion connected devices by 2020, a decrease of 5.3 billion (20.4%) from their 2013 estimate. (It should be noted here that Cisco continues to anticipate as many as 50 billion by 2020).

So, according to Gartner, IoT adoption has not proceeded at the rate they had anticipated at the end of 2013.

One reason for the slower-than-expected growth is the difficulty faced when trying to implement IoT technology. In fact, Gartner anticipates that through 2018, 75% of IoT projects will take up to twice as long as planned.

Value of the IoT

Now, let’s consider the monetary value of the IoT and how that number has progressed. Cisco initially projected a value of $14.4 trillion by 2022. Within two years Cisco had increased this number to $19 trillion.


This highlights an interesting fact. Even though fewer connected devices are expected by this date, the total value of these devices and the underlying network is expected to be greater than it was when more devices were expected. Based on this, I think it’s safe to suggest that implementing IoT technology is turning out to be more expensive than originally thought.

This may be due in part to the fact that some enterprises are rushing headlong into IoT projects without the proper foresight and planning. Often it is a reaction to competitive pressure, based on a perception that a competitor is already moving forward with their IoT strategy, or simply in an effort to be the first and gain a competitive edge.

“I think it’s safe to suggest that implementing IoT technology is turning out to be more expensive than originally thought.”

Another answer may come from Gartner’s 2015 report: “Predicts 2015: The Internet of Things”, in which Gartner predicts that through 2018, there will be “no dominant IoT ecosystem platform”. They cite a lack of IoT standards and anticipate that IT leaders will be forced to compose solutions from multiple providers.

Even when faced with these realities, however, enterprises are still moving forward with their IoT projects. The extra expense – though unanticipated – is not nearly enough to outweigh the potential benefits. The IoT is most certainly transforming the way businesses operate, and no one wants to be the last one to this dance.

IoT Investment

This is an important category as it will largely determine how quickly the industry moves to develop standards, and how motivated IoT solution providers will be to develop more powerful and more cost-effective solutions.
Recall IDC’s projection of annual market revenue reaching $1.7 trillion by 2020. It would stand to reason that if we are learning that IoT projects are coming in over budget and late, there is probably some distaste in the marketplace, and maybe IDC’s projection was a bit ambitious.

At the same time, though, if people are spending more on IoT initiatives than they had originally planned, perhaps IDC’s projection was a bit conservative. Let’s examine how things are taking shape.

In 2015, IDC reported that worldwide IoT spending reached $655.8 billion in 2014 and calculated a 16.9% CAGR (Compound Annual Growth Rate).

Well, 2015 is now in the books and we can see how IDC’s projections seem to be holding up. Their latest report indicates that spending in 2015 reached $698.6 billion, a CAGR over 2014 of only 6.53%. Had IDC’s anticipated CAGR proven accurate, 2015 revenue should have been closer to $766 billion.

Notwithstanding this fact, however, IDC continues to project a CAGR of 17% and an increase in spending to $1.3 billion by 2019, which would equal approximately $1.5 billion in 2020. It looks like IDC sees the IoT market cooling off a bit, though not much.

So, while the earlier projection has proven to be overly optimistic, it is clear that investments in IoT initiatives are continuing to increase with no end in sight.

If there is any kind of meaningful takeaway from all of this, I think it’s safe to surmise that IoT projects may be coming in late and over budget, but that doesn’t seem to have had much of an impact on continued investments. It is clear that business owners and executives see the value and have no interest in letting their competitor’s gain an edge.
So, was the IoT hyped a bit excessively over the last couple of years? Maybe a bit. But, it is also very real and happening right now.
