Alexis is wearing the Shock Collar this morning!

Today's question: Back in 1956… a revolutionary item was created and placed upon store shelves for purchase. It was called “The Lövet,” and it was the first of its kind on the market. Over the next few years... It became so popular that tens of thousands of them sold out all across the world and that helped launch a certain company into global stardom. Today, they have almost 500 locations across 52 different countries, and last year alone had $48 billion in sales! So all this success started thanks to the Lovet (which is not called that today). Tell me, what business did the Lovet help revolutionize?
