Granite started becoming popular for countertops in the late 20th century, particularly in the 1980s and 1990s. Prior to that, other materials like laminate, wood, and tile were more commonly used for kitchen countertops. However, granite gained popularity due to its durability, natural beauty, and heat resistance. As people became more interested in high-end materials and sought a more luxurious look for their kitchens, granite countertops became a desirable choice. The availability of granite in various colors and patterns also contributed to its rising popularity. Since then, granite has remained a popular option for countertops in many homes and continues to be sought after for its aesthetic appeal and durability.
