Chubu-Nippon Broadcasting
On January 7, 2011, "Puella Magi Madoka Magica" debuted on Mainichi Broadcasting System (MBS), Tokyo Broadcasting System (TBS), and Chubu-Nippon Broadcasting (CBC) in Japan. The first ten episodes aired weekly without interruption and were made available for streaming on Nico Nico Douga and BIGLOBE's Anime One service. That March, the planned broadcasts of the last two episodes were halted because of the 2011 Tōhoku earthquake and tsunami; TBS also canceled its scheduled airing of the 10th episode so it could provide more news coverage of the natural disaster.
