In the dark days before
teletext, the BBC post-shutdown was not a haven of bad computer graphics and
DIY store
Jazz. Once the night's TV had ended, the
national anthem would be played (this still happens on
BBC2, occasionally), then the screen would go totally blank except for a white dot in the middle, and an incredibly annoying constant
tone. This was apparently intended to wake up
armchair sleepers and make them turn the TV off, which may otherwise
overheat. The dot would remain in place until the
breakfast news.
The white dot symbolised
the end of television, at least for that night. This is probably why the above organisation have adopted the name. As for the organisation itself, I'd suggest that if you want
freedom from TV, don't buy one, and let other people make their own
choice.
Staring at the TV, about 3AM
Rik: Anyway, what does that white dot mean?
Neil: It means something really heavy. It means... there's no more telly. It's time to go to bed.
