sentences:  Ybor City continued to grow and prosper through the 1920s, by which time its factories were producing almost half a billion hand-rolled cigars every year, giving Tampa the nickname of the "Cigar City".The coming of the Great Depression in the early 1930s brought a sharp reduction in the worldwide demand for fine cigars, and Ybor City's economic base suffered greatly.Some cigar factories closed, others ended the hand-rolled tradition and turned to mechanization to reduce costs, and remaining operations sharply decreased production and payrolls, resulting in widespread unemployment and hardship across the entire neighborhood.
