As with most new concepts, the shopping cart was not immediately embraced by the public. Early on, some retailers even resorted to hiring models to shop with grocery carts as to "model" the behavior desired for customers.
1954 brought the availability of color coordinated cart handles with personalized store names making carts easier to identify in the parking lot and reminding shoppers which chain they were shopping at as they wheeled down the aisles.
Today, retailers also have more choices. For instance, now shopping carts are available with wire or plastic baskets.
Some changes have come because of changing trends in the retail industry. With the rising value of retail floor space, carts are stored outside in the elements more frequently. This has driven the search for better plating and alternate finishes. The retailer can choose between nickel chrome, zinc, or a rust resistant powder coated finish.'
