new formulas, more adult comics like XIII by William Vance and Jean Van Hamme or Jeremiah by Hermann. Most artists of the first generation were no longer active, and the productivity of many artists of the second generation slowed down as well. New talents were Tome and Janry, the new team for the Spirou et Fantasio comic, Bruno Gazzotti (Soda), François Gilson (Mélusine), Bercovici, Zidrou, André Geerts, Bernard Hislaire, Midam (Kid Paddle), Frank Pé, Marc Hardy and Luc Cromheecke. Robbedoes had a severe reduction in the number of readers, and was first reduced to 32 pages (with Spirou growing to 68), before it finally disappeared in 2005. Collections From the very start, Spirou and Robbedoes published collections of 10 to 13 consecutive magazines in hardcover format - originally quarterly, but more frequently with the increased page number of the magazine. This series still continues for Spirou with 371 volumes as of September 2022. Spirou and Tintin rivalry Since the 1940s, Spirou was in constant competition with Tintin magazine . If one artist was published by one of the magazines, he would not be published by the other one. This was a gentleman's agreement between the two publishers, Raymond Leblanc of Le Lombard and Charles Dupuis of Dupuis. One notable exception was André Franquin, who in 1955, after a dispute with its editor, moved from the more popular Spirou to Tintin. The dispute was quickly settled, but Franquin had signed an agreement with Tintin for five years. He created Modeste et Pompon for Tintin while pursuing work for Spirou. He quit Tintin at the end of his contract. Some artists moved from Spirou to Tintin like Eddy Paape and Liliane & Fred Funcken, while some went from Tintin to Spirou like Raymond Macherot and Berck.
