I nteractive media operators seek to deliver broadband Internet access on computer and television screens over cable, satellite and terrestrial broadcast networks, but this is only the beginning. Retailers will use wireless barcode scanning for instant debits, such as in the IBM commercial where the man stuffing products into his trenchcoat is stopped by a security guard because he left the store without his receipt. Devices will be so tiny that a digital source can be embedded imperceptibly into a human body. The goal is full interactivity without the need for screens or keyboards. As an example, Pentland introduced an conference badge with wireless sensors that could tell if another attendee shared common interests, indicated by a green or red light.

Application in home networking, for instance, may include hands-free readouts of cooking recipes or assuring home security at night from the bed. To take advantage of immersive Internet technologies, however, cable operators defined by a coaxial plant may need to rethink their systems.
