Corporate media

MSM is an abbreviation for "Main Stream Media", often considered to be the only credible (though still not necessarily reliable) sources for most of what we know and believe.

The MSM has often carried information tending to undermine "the official version" but does tend to shy away from anything that has possible intelligence implications, such as terrorism.

Some sources believe that the number of untouchable or "third-rail" stories is increasing rapidly with enhanced recognition and fear of terrorism in the general public.

In some cases, eg Andrew Gilligan, peoples employment has been summarily terminated even when there are no obvious secrecy implications to the information and only political embarrassment is involved.
