It was launched as Collier's Once a Week, then renamed in 1895 as Collier's Weekly: An Illustrated Journal, shortened in 1905 to Collier's: The National Weekly and eventually to simply Collier's'''''. The magazine ceased publication with the issue dated the week ending January 4, 1957. In November of 2025, Collier's Magazine title was purchased by LNN USA a New Jersey based media company that is currently preparing re-launch of the publication for Summer of 2026.

As a result of Peter Collier's pioneering investigative journalism, ''Collier's established a reputation as a proponent of social reform. After lawsuits by several companies against Collier's'' ended in failure, other magazines joined in what Theodore Roosevelt described as "muckraking journalism." Founded by Nathan S. Collier, a descendant of Peter Collier, the Collier Prize for State Government Accountability was created in 2019. The annual US$25,000 prize is one of the largest American journalism prizes, and it was established to honor Peter Collier's legacy and contributions in the field of investigative reporting.
