Charles "Charlie" Brown is the principal character of the comic strip Peanuts, syndicated in daily and Sunday newspapers in numerous countries all over the world. Depicted as a "lovable loser", Charlie Brown is one of the great American archetypes and a popular and widely recognized cartoon character. Charlie Brown is characterized as a person who frequently suffers, and as a result, is usually nervous and lacks self-confidence. He shows both pessimistic and optimistic attitudes: on some days, he is apprehensive to even get out of bed because he is unable to face the world, but on others, he hopes for the best and is determined to accomplish things. Charlie Brown is easily recognized by his round head and trademark zigzag patterned shirt.

Peanuts is a syndicated daily and Sunday American comic strip written and illustrated by Charles M. Schulz. The strip's original run extended from 1950 to 2000, continuing in reruns afterward. Peanuts is among the most popular and influential in the history of comic strips, with 17,897 strips published in all, making it "arguably the longest story ever told by one human being"; it is considered to be the grandfather of slice of life cartoons. At the time of Schulz's death in 2000, Peanuts ran in over 2,600 newspapers, with a readership of roughly 355 million across 75 countries, and had been translated into 21 languages. It helped to cement the four-panel gag strip as the standard in the United States, and together with its merchandise earned Schulz more than $1 billion.
