Media-Reich

1. A lengthy period of publicity pursued by agents in popular culture long after the initial reason for their fame has long passed into insignificance. Such a period is charaterised not just by shamless acts of self-publicity but also of some bogus rationalisation made by by certain publications as to the 'meaning' of this enduring fame and its supposed cultural significance.

Examples- There are many, but a full blown Media-Reich as opposed to some desperate clinging on to fame applies to larger scale celebities who wield considerable power within popular culture and have many 'champions' in the media to keep the flame going, in the same way the Third Reich had in Germany in the 1930s, hence the term's emtymology.
Madonna is a prime example of this....
