Igdoof

Igdoof was a comic Jeff Kinney made for the University of Maryland's campus newspaper. It was super popular in college. When he tried to get it in some newspapers after he had graduated from college, he got rejected multiple times. As a result, he decided he would try to make a book, which became Diary of a Wimpy Kid. However, he first published the story idea on Funbrain, in the Diary of a Wimpy Kid (online version) (which can still be read on Funbrain today) to see if people would like the idea of the book Diary of a Wimpy Kid, which was successful.
