I would say that the Pentagon Papers case of 1971 - in which the government tried to block the The New York Times and The Washington Post that they obtained from a secret study of how we got involved in the war in Vietnam - that is probably the most important case.
Maybe the way we have learned to look has changed in the last 25 years, and the exotic is much more acceptable. There are many artists now, younger artists, who work out of the exotic.
