The Internet of Pushed Data to Things
Looks like the digital signage trend isn't going anywhere, which is great news for connected device manufacturers. It's a great area of technology when you think of the sheer footprint of connected signage, from retail to food to just about any other industry.
It makes sense that the focus of the industry is still on "pushing" out data to connected devices, not only can it deliver a bit more from a security perspective since the type of data being used can be controlled a bit more from a security perspective, but it also gets around a lot of the issues with pulling information from sensors and the privacy and security risks that come with it.
I expect we'll see the same continued growth for a few more years at least in the digital signage market.
