If we could wrestle everyone to the ground individually, we would make much more of an impression. Well, now we can. Narrowcast is just the opposite of broadcast. Its defining characteristic is that each recipient can receive a different message, simultaneously or not. The modern telephone in normal usage is a synchronous narrowcast device.
Individual humans use it to communicate with other individuals.
The link established between them via the phone system is a point to point connection, and the system as a whole is a narrowcast medium. The Internet is much more like the phone system than like the cable system because it facilitates point to point connections. The Internet is a narrowcast medium. We can t blame them, though. Undisputed masters of a medium that smothers our culture with a heavy broadcast blanket, Hollywood is accustomed to putting a lot of money into the production of mass- market schlock.
