Overview
Californication is a portmanteau of California and fornication, appearing in Time on May 6, 1966 and written about on August 21, 1972, additionally seen on bumper stickers in the U.S. states of Idaho, Washington, Colorado, Oregon, Oklahoma, and Texas.
It was a term popular in the 1970s and referring primarily to the "haphazard, mindless development [of land] that has already gobbled up most of Southern California", which some attributed to an influx of Californians to other states in the Western United States.
As a popular concept
One of the most well-known uses of the word occurs in the Red Hot Chili Peppers's album Californication (1999), which has a song by the same name. The song refers to a Hollywood-driven exportation of culture, with further references to plastic surgery, war, population control, and natural disasters.
The concept is also familiar within the social sciences, and is understood as American cultural imperialism emanating from California. This Californication is a particular ethos packaged as a cultural commodity and broadcast throughout the world in order to penetrate into other cultures.
