A comic strip is a sequence of drawings arranged in interrelated panels to display brief humor or form a narrative, often serialized, with text in balloons and captions. Traditionally, throughout the 20th century and into the 21st, these have been published in newspapers and magazines, with horizontal strips printed in black-and-white in daily newspapers, while Sunday newspapers offered longer sequences in special color comics sections. With the development of the internet, they began to appear online as webcomics. There were more than 200 different comic strips and daily cartoon panels in American newspapers alone each day for most of the 20th century, for a total of at least 7,300,000 episodes.
The Biblia pauperum ("Paupers' Bible"), a tradition of picture Bibles beginning in the later Middle Ages, sometimes depicted Biblical events with words spoken by the figures in the miniatures written on scrolls coming out of their mouths—which makes them to some extent ancestors of the modern cartoon strips.
In China, with its traditions of block printing and of the incorporation of text with image, experiments with what became lianhuanhua date back to 1884.
