The next time you go to the grocery store, consider the ordinary shopping cart as something more than a rattling basket blocking your parking space.
In the 1930s, an American grocer named Sylvan Goldman invented the precursor to the modern day shopping cart, using a folding frame that was fixed on a set of wheels. He hoped that people would buy more groceries if they did not have to carry heavy baskets as they browsed.
And they did.
But over the decades, the shopping cart has evolved from its mundane existence as the centerpiece of every grocery store run.
