Cisco (CSCO 2.11%) CEO John Chambers took the stage at last week's prestigious Consumer Electronics Show to talk about his $19 trillion -- yes, trillion -- vision for the Internet of Things.
Cisco is a leader in the space and is guaranteed to benefit as machines start talking more to other machines without human interaction. IBM (IBM 0.67%) also leans heavily on this massive market, and you wouldn't believe how much data a General Electrics' (GE 2.37%) airplane engine or locomotive can pump out over wireless links. That's three Dow (^DJI 0.71%) stocks chasing the same opportunity from different angles.
Nineteen trillion dollars is about the size of the U.S. debt ceiling, or of America's annual gross domestic product. In the video below, Fool analyst Anders Bylund tells Mike Klesta why Chambers might have picked an unrealistically high market value, even if the Internet of Things is almost certainly the right bet for the three Dow titans.
