Digital compression will allow television companies to squeeze more channels into the same bandwidth.

ECONOMIST: Digital television

As the technology of digital compression develops, the concept of the channel will become meaningless.

ECONOMIST: As the audience gets smaller, it will also get more powerful

Digital compression typically allows between eight and 12 channels to occupy the same capacity required by a single analogue channel.
