The heart-shaped conversation candies to be called Sweethearts got their start in 1901. Other styles were formerly produced such as lozenges, postcards, horseshoes, watches, and baseballs. As of 2010, the classic pastel candy formula is abandoned. Sweethearts are now softer candies with vivid colors and all new flavors, which are more intense and even a bit more sour. These new flavors include sour apple, strawberry, and "spring fresh. " Line extensions carrying the Sweethearts brand include chocolates and sugar-free hearts.
