> His novels, most of them published in monthly or weekly instalments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication.[4][5] Cliffhanger endings in his serial publications kept readers in suspense.[6] The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback.[5] For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her disabilities, Dickens improved the character with positive features.[7] His plots were carefully constructed and he often wove elements from topical events into his narratives.[8] Masses of the illiterate poor would individually pay a halfpenny to have each new monthly episode read to them, opening up and inspiring a new class of readers.
