ALL STARS SNOOPY CHARLIE BROWN, Social Studies Expert 43 The First and Funniest Comic Strip NU T NO.0816 ALL STARS ★ CHARLIE A Courtesy of andertoons/flickr P eanuts is one of the most popular comic strips of all time. First appearing on October 2, 1950, Peanuts eventually ran in more than 2,600 newspapers in 75 countries. The comic had a major influence on other strips by making the four- panel comic strip the standard in American newspapers. Charlie Brown and Snoopy are just 15 two of the many characters created by cartoonist Charles M. Schulz. Like Charlie Brown, Schulz was a very shy boy in school. He also felt like a failure when his high school refused to put his 20 artwork in its yearbook. Even so, he learned to carry on through hard times. 5 The main character of Peanuts is the shy, lovable loser Charlie Brown. It seems that whatever Charlie Brown tries to do, he fails. Whenever he flies a kite, it gets stuck in a tree; he loses every baseball game; he never receives any cards on Christmas or Valentine's Day. Nonetheless, he wins over the reader's heart because he never gives up hope and never stops trying. Another popular character in Peanuts is Charlie Brown's dog, Snoopy. Snoopy 10 is a beagle with a vivid imagination. Sitting atop his doghouse, he daydreams about being a World War I jet pilot, a best-selling author, and "Joe Cool," a cool college student. Also, even though he's just a dog, he's the best player on Charlie Brown's baseball team. ▲ Charles M. Schulz 127
