The story of the 1800-Flowers.com online store is interesting because it traces the path that a Manhattan flower shop bought in the 1970s for $ 10,000 to a multimillion business that generated $ 1.2 bn. in sales just last year. The achievement goes through impressive AI innovation that has cemented its leadership position in the US online marketplace.
