About four years ago, Microsoft's Research and Development team came up with a new technology called Smart Personal Object Technology (SPOT) that uses FM radio signals to broadcast news, weather and other information to wristwatches. The first Smart Watches leveraging SPOT were first launched last January at the Consumer Electronics Show however it did take them a few extra months to get the wireless service running with all its features and have wristwatches available more widely.
