No. "Brainwashing" is a very trixy concept anyway. Am sure the KGB/CIA are past masters but for me the term implies long term, sustained, force, cruelty, deprivation and the exclusion of other points of view. Would have to take place in a closed institution of some sort,
The media is one of many influences in our lives and merely tweaks our world view.
Probably brainwashing is too strong a word, bbh, although it is used more loosely now than originally, when it probably came from KGB/CIA methods. I do think, however, that the media has a much stronger influence than many of us realise, and does more than just tweak. You only have to think of the way Andy was portrayed in our papers and how many people went along with it until recently.
