Sliced Bread, But When?

"The best thing since sliced bread." - but when was 'sliced bread'?

On Saturday July 7th, 1928, the Chillicothe Baking Company in Chillicothe, Missouri, made history by selling the first pre-sliced bread using a machine created by Otto Frederick Rohwedder. So, everything since July 7th, 1928 is "since sliced bread". 

Many sources say the first record of the idiom is thought to be in 1952, when the famous comedian Red Skelton said in an interview with the Salisbury Times: “Don’t worry about television. It’s the greatest thing since sliced bread.”

However, one source found it used in The Northern Whig (Belfast, Ireland) of Thursday 8th March 1951, which quoted the American journalist Dorothy Kilgallen (1913-65) writing in the New York Journal-American about British film actor Stewart Granger. In the article, Kilgallen’s sister is quoted as saying: “He is the greatest thing since sliced bread!”

And boy-o-boy does the town of Chillicothe (pronounce that!) loved to talk about it, ha ha ha.
