The strip developed a series of formulas that ran over its course to facilitate a wide range of stories. The earlier strips relied on a formula by which Daddy Warbucks is called away on business and through a variety of contrivances, Annie is cast out of the Warbucks mansion, usually by her enemy, the nasty Mrs. Warbucks. Annie then wanders the countryside and has adventures meeting and helping new people in their daily struggles. Early stories dealt with political corruption, criminal gangs and corrupt institutions, which Annie would confront. Annie ultimately would encounter troubles with the villain, who would be vanquished by the returning Daddy Warbucks. Annie and Daddy would then be reunited, at which point, after several weeks, the formula would play out again. In the series, each strip represented a single day in the life of the characters. This device was dropped by the end of the ’20s.
