Greatest Thing Since Sliced Bread

1940 explores the origins of
common products and phrases.

I wonder what was the greatest thing before sliced bread?

But I was also wondering where this saying came from, and of course, where was its First Mention?

Turns out it was mom.

Or more precisely, some advertising maverick thought it up and attributed it to mom,. The phrase had its First Mention on February 16, 1940 in the Burlington Daily Times-News.

And here it is in all its glory.

Our FirstMention research is carried out in many sources, including historical newspaper archives, online family history records, state archives, and old books.
