The filtered version was introduced in 1966, followed by Chesterfield 101s in 1967 (the latter being relaunched, along with Chesterfield 100s, in 1983). Chesterfield Lights were brought out in 1988.
The name of the Liggett & Myers Tobacco Company was changed to the Liggett Group in 1976. In 1978, Liggett sold the international rights of their brands to Philip Morris International. Twenty-one years later, Philip Morris U.S.A. (now Altria) purchased the American rights to Liggett's Chesterfield, L & M and Lark brands. Philip Morris still manufactures Chesterfield today as a discount brand and also Marlboro cigarettes.
