Back in 2004 we took a brief look at an emerging technology called SPOT (Smart Personal Objects Technology) that used FM radio broadcast signals to deliver tidbits of content to small devices like smart watches. Backed by Microsoft and a number of partners, SPOT devices found its way into consumer hands during those days.
Fast forward until today, the essence of what SPOT intended to do was perhaps before its time, and it's been PDAs but mostly cell phones that have become the preferred mediums for real-time information updates on the go. This week SPOT watches were officially discontinued, though there's mention that the underlying technology may continue to be used by Garmin and Windows Mobile products.
