Popcorn chicken was invented by food technologist Gene Gagliardi. It was test-marketed in the United States from March 1992, and had been launched nationwide by September 1992. It has been periodically available in KFC outlets. It was re-introduced in the US in 1998, and again in 2001. It was later re-introduced once again in 2015, under the name "KFC Popcorn Nuggets".
