It did impact the way in whhich advertising dollars were spent, and so I guess you may be right, bbut there was no specialization phase there, it replaced the way something had been done in the past.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
