Here's a decent analysis of this crap (found this on gzip site long ago):

The terminology used here is misleading, there are too many terms and not enough meaning. For example 'random' versus 'noisy':
White noise:
Quote:
White noise is a random signal (or process) with a flat power spectral density. In other words, the signal's power spectral density has equal power in any band, at any centre frequency, having a given bandwidth. White noise is considered analogous to white light which contains all frequencies.
An infinite-bandwidth, white noise signal is purely a theoretical construction. By having power at all frequencies, the total power of such a signal is infinite. In practice, a signal can be "white" with a flat spectrum over a defined frequency band.

The problem is that white noise does not exist, but if it did, it could not be broadcast, and anything coming close is very difficult to broadcast.
Anyway, remember that compression is a misnomer here, it's not like in real life:
Take a box full full of documents and reduce its size by any means. So you burn it. Good, but your data is lost.
Compression is just optimization to reduce redundancy. Any data on a computer still has a minimal size one with lowest redundancy.
Say you were to store the number 2 in binary on a disk, it would be 10, there is no way to compress this to just one bit. The foolish article referenced above says you can, so go ahead
