What is "collier's"

Collier's was an American magazine, founded in 1888 by Peter Fenelon Collier. It was initially launched as Collier's Once a Week, then changed in 1895 to Collier's Weekly: An Illustrated Journal, and finally shortened in 1942 to simply Collier's. The magazine ceased publication with the January 4, 1957 issue, though a brief, failed attempt was made to revive the Collier's name with a new magazine in 2012.

As a result of Peter Collier's pioneering investigative journalism, Collier's Weekly established a reputation as a proponent of social reform. When attempts by various companies to sue Collier ended in failure, other magazines became involved in what Theodore Roosevelt described as " muckraking journalism."
