Answer: Marlboro
Marlboro is the largest selling brand of cigarettes in the world. It is made by Philip Morris USA (a branch of Altria) within the US, and by Philip Morris International (now separate from Altria) outside the US. It is famous for its billboard advertisements and magazine ads of the Marlboro Man.
The brand is named after Great Marlborough Street, the location of its original London Factory. Richmond, Virginia is now the location of the largest Marlboro cigarette manufacturing plant.
