supermarket

A supermarket is a self-service shop offering a wide variety of food, beverages and household products, organized into sections under one roof. The supermarket retail format first appeared around 1930 in the United States as the culmination of almost two decades of retail innovations to the grocery store, and began to spread to other countries after extensive worldwide publicity in 1956. In everyday American English usage, "grocery store" is often used interchangeably with "supermarket", while in other regions a supermarket is larger and has a wider selection, but is smaller and more limited in the range of merchandise than a hypermarket or megastore, which developed decades later.

The supermarket typically has places for fresh meat, fresh produce, dairy, deli items, baked goods, and similar foodstuffs. Shelf space is also reserved for canned and packaged goods and for various non-food items such as kitchenware, household cleaners, pharmacy products and pet supplies. Some supermarkets also sell other household products that are consumed regularly, such as alcohol (where permitted), medicine, and clothing, and some sell a much wider range of non-food products: DVDs, art supplies, sporting equipment, board games, and seasonal items (e.g., Christmas wrapping paper, Easter eggs, school uniforms, Valentine's Day themed gifts, Mother's Day gifts, Father's Day gifts and Halloween).
