Philip Morris, a London-based cigarette manufacturer, created a New York subsidiary in 1902 to sell several of its cigarette brands, including Marlboro. By 1924 they were advertising Marlboro as a woman's cigarette based on the slogan Mild As May.
They built a factory and made 10 million cigarettes their first year and about one billion cigarettes five years later. The first brand of cigarettes were packaged in a box with baseball cards and were called Duke of Durham.is hand-rolled cigarettes were sold to soldiers at the end of the Civil War.
