>> ERIC: IT'S 7:52 P.M. ON FRIDAY NIGHT, AND THAT MEANS IT'S "ALMANAC" HISTORY TIME.

LAST WEEK, CATHY ASKED YOU ABOUT A COMPANY FOUNDED IN MINNEAPOLIS IN 1951.

IT WAS AN EARLY PLAYER IN WHAT IS NOW A MULTIBILLION-DOLLAR INDUSTRY.

A PROCESS THAT THIS COMPANY DEVELOPED AND PATENTED IN 1979 SOLVED A SIGNIFICANT PROBLEM THAT THE INDUSTRY FACED AT THE TIME.

WE ASKED YOU TO TELL US WHAT COMPANY WAS GRANTED A PATENT IN 1979 THAT REVOLUTIONIZED THEIR INDUSTRY?

AND OF COURSE WE WANTED TO KNOW WHAT THE PATENT WAS FOR.

WE ADDED IN A LOT OF FOOD HINTS.

BUT THAT DIDN'T HELP THESE FOUR VIEWERS.

>> ERIC: AT LEAST A COUPLE OF THOSE ANSWERS WERE FOOD-RELATED.

BUT ALL OF THEM WERE WRONG.

FOR THE RIGHT ANSWER THIS WEEK, WE TURN TO LONGTIME VIEWER AND INDEX FILE AFFICIONADO MITCHELL, WHO REGULARLY WRITES POEMS FOR US.

>> Eric: CRISP CRUST.

THANK YOU, MITCHELL, FOR THAT FINE VERSE.

YES, TOTINO'S PIZZA AND THEIR PATENT ON CRISP CRUST TECHNOLOGY WAS THE ANSWER WE SOUGHT.

THANK YOU TO PRODUCER JIM BICKAL FOR PROVIDING THIS FINE HISTORY QUESTION.

WE HAVE JUST ENOUGH TIME FOR SOME MUSICAL HISTORY FOR YOU.

30 YEARS AGO THIS WEEK, TINA AND THE B-SIDE MOVEMENT APPEARED ON TPT'S MUSIC SERIES "SHOWCASE."

TAKE A LISTEN, AND WE'LL SEE YOU NEXT WEEK.

AND BE CAREFUL.
