Capitalizing on consumer demand for a sweet product that tasted like ice cream but was healthier, TCBY opened its first store in 1981. Unlike previous pre-packaged versions introduced earlier, TCBY's yogurt was soft-serve dispensed at the point of sale through a machine. TCBY became the largest frozen yogurt franchise in the world at that time. As others saw the success of TCBY, frozen yogurt took off in the 1980s, reaching sales of $25 million in 1986. Brands such as Colombo, Nanci's, and Miss Karen's came to prominence around that time in the United States and frozen yogurt was 10% of the frozen dessert market accounting for over $300 million in sales by the mid 1990s. Demand for frozen yogurt slowed considerably in the late 1990s as Americans turned their attention to high-protein, high-fat diets. Low-fat foods such as frozen yogurt fell out of favor as food trends favored higher fat and lower cost ice cream at the turn of the millennium.
