Ever buy it, make your own pizza back in the day, 60 years ago? I did. Don't recall how I and others in rural Minnesota even became aware of it. TV ads, probably.
My first real pizza (1962), at a small restaurant in Moorhead, MN was sheer delight. OMG, it was good! Couldn't wait to bite into it, burned the roof of my mouth several times.
I thought the rapid growth of pizza restaurants and grocery store frozen pizzas would wipe out Chef B's business in short order. I was wrong. Most grocery stores have it in stock.
Hector Boiardi started his pizza and pasta business in 1928, changing his last name to a more phonetic version. He built a factory in Milton, PA, and hit the jackpot in WW II, producing 250,000 cans a day for the troops. The C-rations I ate in Vietnam probably included some products from that factory. The brand is now owned by Conagra Foods: https://www.chefboyardee.com/
