Retronovation: "The conscious process of mining the past to produce methods, ideas, or products which seem novel to the modern mind. Some recent examples include Pepsi Throwback’s use of real sugar, Pepsi Natural’s glass bottle, and General Mills’ introduction of old packaging for some of their cereals." (Source: Kottke.) A portmanteau of retrospective and innovation.
Retronovation was coined in early March 2009 by Tim (no last name given), who represents half of the Snarkmarket blog. (Tim clearly relishes neologism; his blog's archives are "snarkives," posts about food are "gastrosnark," and each post's permanent URL is a "permasnark.") After Kottke picked it up, Tim commented in a follow-up post about the word's genesis:
Tim, whose Blogger profile identifies him as a PhD student in Philadelphia, also maintains a second blog about culture and politics, Short Schrift. (Maybe his last name is Schrift?) Both blogs are intelligent, amusing, and well worth your time.
