Krispy Kreme is the doughnut chain famous for its illuminated Hot Now sign indicating that fresh doughnuts are available.
The chain began in Winston-Salem, North Carolina, in 1937, when Vernon Rudolph opened the first Krispy Kreme shop. Its signature product is the Original Glazed doughnut, which is made on an automated production line and served warm at participating shops.
The Hot Now sign became a recognizable part of the brand’s identity. When illuminated, it signals that freshly made doughnuts are coming off the production line or are available for customers.
The sign is not a universal promise that every doughnut in the shop is still warm. Availability and sign practices can vary by location, especially in supermarkets, kiosks, and franchised outlets.
