History Of Manga-about Gekiga(2):- Not only was the story telling in gekiga more serious but also the style was more realistic. Gekiga constitutes the work of first generation of Japanese alternative cartoonists. Some authors use this original definition to produce works that only contained shock factor. As a result of Tezuka adopting gekiga styles and story telling, there was an acceptance of a wide diversity of experimental stories into the mainstream comic market commonly referred to critics as being the Golden Ageof Manga. This started in the 1970s and continued into the 1980s. In 1977, writer Kazuo Koike founded the Gekiga Sonjuku educational program, which emphasized maturity and strong characterization in manga. As mainstream shōnen magazines became increasingly more commercialized, gekiga's influence began to fade. More recently the most mainstream shōnen publications have lost a lot of gekiga influence and these kinds of works are now found in slightly more underground publications (usually seinen magazines). In addition other artistic movements have emerged in alternative mangalike the emergence of the avant-garde magazine Garoaround the time of gekiga's acceptance into the mainstream manga market and the much later Nouvelle Mangamovement. These movements have superseded gekiga as alternative comicsin Japan.
