17 Ways Grocery Stores Have Changed Over the Past 50 Years

The supermarket has been a staple of American life ever since the first one, a Piggly Wiggly, opened in Memphis, Tennessee, in 1916. Ever since, we've scoured the aisles in a quest to fill our pantries without overpaying. And while they may look much the same on the surface, grocery stores continue to evolve as our shopping habits change. From the disappearance of green stamps to the rise of online ordering, here's how our local supermarkets have changed over the past several decades.

In the '60s and early '70s, most grocery stores were a compact 10,000 to 15,000 square feet; today, they average 45,000 square feet, according to Grocery Dive. In fact, at some of the biggest supercenters, it might feel like it takes 10 minutes just to walk to the back corner for a gallon of milk. If that's a pet peeve, take heart: There's some evidence that the pendulum is swinging back the other way, with many retailers debuting smaller-format locations that appeal to customers who want to shop more quickly and efficiently.

If you've ever felt overwhelmed by the sheer number of cereals or salad dressings on the shelves, you're not alone. Grocery shoppers have tons more products to choose from than they did in decades past, up from an average of just under 9,000 products in the mid '70s to almost 47,000 in 2008, according to industry executives. If you find all the choices excessive, keep this in mind: Stores like Aldi that offer far fewer products are becoming increasingly popular with shoppers.

In the '70s and '80s, chances are you shopped at a local or regional grocery chain, but the past couple of decades have been marked by industry consolidation. For instance, by 2009, the nation's top four food sellers sold more than half of its groceries, double the proportion that they sold a decade prior. Today's grocery industry is dominated by mega chains like Kroger, Walmart, and Albertsons, companies that are poised to continue gobbling up smaller regional and specialty chains to improve their bottom lines.

In the 1950s, your local supermarket may have only kept its doors open beyond daytime hours for one evening a week; Sunday hours were still almost unheard of. The early '70s brought stores that stayed open 24 hours a day, 7 days a week, but that was the case for only a small fraction of the nation's most profitable markets. Today, there are plenty of 24-hour groceries out there, but the rise of e-commerce means the pendulum is swinging back toward slightly more limited hours. You'll still have plenty of shopping time: Many Krogers, for instance, open at 5 or 6 a.m. and don't close until midnight or 1 a.m.

While organic farming took off in the 1970s, grocery stores were slow to catch on, as were federal regulators: Final rules on what actually constituted "organic" food weren't even in place until 2002. But the rest is history, with sales of organics climbing from $8.6 billion that year to more than $49 billion in 2017. Today, shoppers can find organic choices in almost every aisle, and that's not just at huge chains like Kroger and specialty retailers like Whole Foods. Even low-cost groceries like Aldi are getting in on the action.

You're also far more likely to see locally grown or sourced products at your supermarket today than 50 years ago, when local produce and other foods were almost exclusively found at roadside stands and farmers markets. Today, those outlets face competition from huge chains like Whole Foods, though buyers should note that big stores' definitions of "local" may differ from their own (Kroger, for instance, has said it will slap a local label on food sourced from as far as 400 miles away).

In the '70s and '80s, grocery stores often corralled generic products into their own aisles, and ultra-plain packaging reinforced the perception that these cheaper buys were lesser quality. Today, you can find store brands vying for your money alongside the biggest national brands, and younger shoppers who have less name-brand loyalty aren't shy about snapping them up, helping fuel private-label growth. Stores like Aldi and Trader Joe's that almost exclusively sell private labels have also helped eliminate any stigma of buying store brands.

While your local grocery may have had an "ethnic aisle" 50 years ago, the contents were likely anything but. As Epicurious notes, supermarkets catering to white suburbia may have considered global cuisine something along the lines of spaghetti sauce or canned La Choy noodles. Today, selection is much improved, particularly in areas with a more multicultural population, and some larger chains are opening entire stores focused on ethnic products to compete against smaller mom-and-pop markets.

It's hard to believe that 50 years ago, grocery clerks were sticking price tags on nearly every product, and check-out clerks had to manually enter prices to figure out your total. But 1974 saw the first successful test of barcodes at an Ohio grocery store, streamlining the process of both stocking and buying groceries. Today, a visit to your local Aldi will show you just how efficient this process can be — the German grocery chain plasters its products with barcodes so that clerks can scan them as quickly and efficiently as possible.

Of course, the barcode has enabled another innovation that would seem downright alien to shoppers of the '60s and '70s: self-checkout. At virtually all large chains, today's shoppers can scan their items themselves in self-checkout lanes, which is especially convenient for small orders. Some stores are even taking the technology one step further, allowing shoppers to scan items as they shop with their own smartphones and pay with a previously saved credit card to eliminate the need to "check out" at all.

In the '60s and early '70s, almost everyone had a drawer full of S&H Green Stamps that they'd earned by making purchases at the local grocery store. The stamps could be collected and traded in for various merchandise — for instance, three books of stamps for a crystal wine glass set, or a whopping 150 books for a color TV. The stamps gradually faded away in the '80s and '90s as stores turned to cheaper ways to attract and retain customers, including double coupon offers and today's ubiquitous store loyalty cards.

In the '70s, even the most loyal shopper could make their purchases with some degree of anonymity, but today's grocery stores have made tracking what you buy into an art form. The loyalty cards that allow access to sale prices and other special offers also mean stores get detailed data on what we buy and how often. While most shoppers don't mind the personalized coupons and offers that result from this data gathering, our information is also sold to third-party companies who can use it as they wish — a practice that gives many shoppers pause.

While some shoppers may remember a time when grocery clerks eagerly wheeled groceries out to their cars, that service has largely faded away. Its modern counterpart, however, doesn't even require you to get out of your car. Grocery stores are going all in on BOPUS services — that is, buy online, pick up in-store — that let you pull up outside and wait for a clerk to bring your groceries to you for a small fee. No longer a novelty, curbside pickup locations nearly doubled among leading grocers in 2018, and analysts expect the service to rake in $35 billion by 2020.

In the '60s and even early '70s, home delivery of groceries wasn't totally unheard of, but it was in decline. The milkman delivered to close to 30% of U.S. households in the early '60s, but just 7% by the mid-'70s, largely thanks to the advent of much larger refrigerators. Of course, because of the internet, the luxury of home delivery is back, and major chains offer delivery in as little as an hour. Online grocery purchases are projected to reach $38 billion in 2021, up from just under $20 billion this year.

Fifty years ago, grocery stores sold food and not much else; today, many of them are one-stop shops where you can also fill a prescription, cash a check, get a physical, drop off your dry cleaning, buy your grandchild a toy, and pick up a fresh bouquet of flowers. It wasn't until the '80sthat many stores amassed enough square footage to offer these diverse services, now the norm at the nation's "supercenters." The format is best exemplified by Walmart, the nation's biggest retailer and its largest food seller, too.

Decades ago, the only "experience" you could count on at the supermarket was listening to bland elevator music as you perused the cereal aisle. Today, as more customers head online for their purchases, grocery stores have recognized that they need to make shopping more interactive and enjoyable, turning supermarkets into destinations. Two common ways they're accomplishing that: The addition of in-store bars serving up wine and beer, and cooking demonstrations that show shoppers how to whip up a quick meal with the ingredients that surround them.

Though the 1970s saw the continuing rise of frozen foods and other convenience products, recent years have seen massive growth in grocery stores pushing prepared and ready-to-eat meals. It's easy to see why: In the early 1980s, 75% of dinners eaten at home were actually made at home; a few decades later, that number was less than 60%. Grocery stores have been all too happy to hawk an increasingly diverse slate of no-real-cooking-required food, including traditional grab-and-go deli fare and more exotic options like wood-fired pizzas and store-made sushi.
