Sure! I can help answer those questions.  

Pineapple pizza is widely credited as having been first created in 1962 by Sam Panopoulos, a Greek immigrant to Canada.

While pineapple pizza began in Canada, it quickly caught on elsewhere. Although in no place is it known to be considered a "delicacy", pineapple pizza can be found in America, Germany, Britain, Australia, and countless other countries, with quite a following. In fact, TIME Magazine designated pineapple pizza as one of The 13 Most Influential Pizzas of All Time. 

Most influential doesn't mean most loved, though, and the popularity of pineapple pizza varies widely around the world. Pineapple pizza lovers and pineapple pizza haters stand firmly divided, according to research, especially in America and Australia. Britain, however, may be the closest place to revering pineapple pizza as a "delicacy". One survey found that it was the most widely available pizza to Britons. Nearly 4,000 pizzerias throughout the region offer pineapple as an available topping. In contrast, pineapple pizza is so controversial in Iceland, that it was nearly banned, albeit in a political stunt.

I hope this answers your curiosities about the creation date and delicacy status of pineapple pizza. Have a slice on my behalf if you get a chance!

Is there anything else you would like to know about pineapple pizza or any other topic?
