Television Quotes - page 97
TV is unbalanced-if I own a TV station, and you own a television, I can speak to you, but you can't speak to me. Phones, by contrast, are balanced; if you buy the means of consumption, you automatically own the means of production. When you purchase a phone, no one asks if you just want to listen, or if you want to talk on it too. Participation is inherent in the phone, and it's the same for the computer. When you buy a machine that lets you consume digital content, you also buy a machine to produce it. Further, you can share material with your friends, and you can talk about what you consumed or produced or shared. These aren't additional features; they are part of the basic package.
