Early national attention to trick-or-treating was given in October, 1947 issues of the children's magazines "Jack and Jill" and "Children's Activities", and by Halloween episodes of the network radio programs "The Baby Snooks Show" in 1946 and "The Jack Benny Show" and "The Adventures of Ozzie and Harriet" in 1948. Trick-or-treating was depicted in the "Peanuts" comic strip in 1951. The custom had become firmly established in popular culture by 1952, when Walt Disney portrayed it in the cartoon "Trick or Treat", and Ozzie and Harriet were besieged by trick-or-treaters on an episode of their television show. In 1953 UNICEF first conducted a national campaign for children to raise funds for the charity while trick-or-treating.
