In which year was the American cereal "Cookie Crisp" introduced?

"Cookie Crisp" is a breakfast cereal that is made to look like chocolate chip cookies. It is produced by General Mills in the United States and Cereal Partners in other countries. Introduced in 1977, it was originally produced by Ralston Purina until they sold the trademark to General Mills in 1997.

From its introduction in 1977 until the early 1990s, "Cookie Crisp" was available in three varieties: "Chocolate Chip Cookie Crisp," "Vanilla Wafer Cookie Crisp" and "Oatmeal Cookie Crisp."

The first Cookie Crisp mascot, Cookie Jarvis, was introduced in 1977. A wizard in the Merlin mold, he magically turns cookie jars into cereal bowls with a wave of his wand and rhyming incantations. He was voiced by Lennie Weinrib.

In 1980, Cookie Jarvis was joined by Cookie Crook, an anti-hero robber who attempts to steal the "Cookie Crisp;" in 1984 he was followed by his opponent, The Cookie Cop (full name Officer Crumb), a policeofficer) with an Irish accent who thwarts the Cookie Crook's attempts to steal the "Cookie Crisp."

A typical ad would begin with the Cookie Crook attempting to steal the cereal from a live-action breakfast table; often he and the Cookie Cop were portrayed as no larger than mice, so their pictures on the cereal bowl were "life-size". The Crook would have some new gadget or scheme to steal the cereal, but then the Cookie Cop would arrive and save the kid's cereal in the nick of time.
