almost every family today have a TV, in fact probably more than one, and people everywhere spend hours watching it. But a few families choose to live without a TV because they think there are advantages.
The first advantage is that families spend more time talk to each other. Secondly, they spend more time doing more creative things like reading or painting. Thirdly, they spend more time outdoors, and are usually more fit.
But on the other hand, there are also disadvantages. For example, children who don't have a TV may feel different from there school friends, and often won't know what they are talking about. Also, it is not true that all TV programmers are bad. There are good ones, like documentary, and people who live without a TV may know less about what's happening in the world.
In conclusion, although living without a TV has some advantages, I think today it's unrealistic and that we should just try to turn the TV out when there's nothing good on.
