Doraemon is a Japanese manga series created by Fujiko F. Fujio (the pen name of Hiroshi Fujimoto) which later became an anime series and an Asian franchise. The series is about an earless robotic cat named Doraemon, who travels back in time from the 22nd century to aid a schoolboy, Nobita Nobi.
The series first appeared in December 1969, when it was published simultaneously in six different magazines. In total, 1,344 stories were created in the original series, which are published by Shogakukan under the Tentōmushi manga brand, extending to forty-five volumes. The volumes are collected in the Takaoka Central Library in Toyama, Japan, where both Fujiko Fujio were born.
Viz Media bought the license to the Doraemon manga in the 1990s for an English-language release, but canceled it without explanation before any volumes were released. However, Doraemon: Nobita's Dinosaur 2006 (The 26th film in the franchise) got a private screening in Washington D.C. in November 2008.
A majority of Doraemon episodes are comedies with lessons regarding values such as integrity, perseverance, courage, family and respect for elders. Several noteworthy environmental issues are often visited, including homeless animals, global warming, endangered species, deforestation, and pollution. Miscellaneous educational topics such as dinosaurs, the flat Earth theory, wormhole traveling, Gulliver's Travels, and the history of Japan are often covered. (Wikipedia)
