In which year was the Fry's Creme Egg renamed as the Cadbury Creme Egg?

Cadbury Creme Egg (originally named Fry's Creme Egg) is a chocolate confection produced in the shape of an egg. It originated from the British chocolatier Fry's in 1963 before being renamed by Cadbury in 1971. The product consists of a thick chocolate shell containing a sweet white and yellow filling that resembles fondant. The filling mimics the albumen and yolk of a soft boiled egg.

The confectionery is produced by Cadbury in the United Kingdom, by The Hershey Company in the United States, and by Mondelez International in Canada.

Cadbury Creme Eggs are manufactured as two chocolate half shells, each of which is filled with a white fondant made from sugar, glucose syrup, inverted sugar syrup, dried egg white and flavouring. The fondant in each half is topped with a smaller amount of the same mixture coloured yellow with paprika extract, to mimic the yolk and white of a real egg. Both halves are then quickly joined and cooled, the shell bonding together in the process. The solid eggs are removed from the moulds and wrapped in foil.
