i.e., stories featuring Disney characters (from Mickey Mouse and Donald Duck universes). After the 1960s, American artists of Disney comics, such as Carl Barks and Floyd Gottfredson did not produce as many stories as in the past. At present American production of new stories has dwindled (Don Rosa publishes in Europe), and this niche has been filled by companies in South America, Denmark and Italy. The Italian 'Scuola disneyana' has produced several innovations: building the Italian standard length for stories (30 pages), a pocket book format with 3 strips a page, reinterpreting famous works of literature in 'Parodie', long stories up to 400 pages. Among the most important artists and authors are Marco Rota, Romano Scarpa, Giorgio Cavazzano, Massimo De Vita, Giovan Battista Carpi and Guido Martina. The best known Disney character created in Italy is Paperinik (known as Duck Avenger or Phantom Duck to English audiences). Italy prints around 8000 pages of new Disney stories per year, exported worldwide (it makes up 50% of the total production). The main publication, digest size Topolino, prints only new stories every week, but there exist 32 different series of reprints going on, for 30 million of copies sold each year. Since the late 1990s, Disney Italia produced innovative series like PK (Paperinik stories with an American superheroes flavour), W.I.T.C.H. or Monster Allergy.
