- Dueling Dubs: The manga was originally released digital-only in 2013 by Hivelinx before transferring to Digital Manga's eManga service, featuring a heavily panned translation that was very literal in style and accused by fans of reading very dry on top of its sloppy presentation and numerous typos. In 2016, a successful Kickstarter campaign was raised for a physical release and a digital reissue featuring a newer, and far more professional, translation that was released in 2018-2019.
- Keep Circulating the Tapes:
- The original manga was this for years among English-speaking fans until it was finally licensed in 2013.
- AnimEigo's license to the TV series, OVAs, and first movie expired in 2004, and they were out-of-print for 15 years until Discotek Media reissued them on Blu-ray in 2019. The series is also now available for streaming on Retro Crush.
- ADV's license to the second movie also expired some time ago, but it remains out-of-print (although used DVD copies aren't usually too expensive).
- The original Jump special was never licensed for an overseas release nor released on home video in Japan aside from VHS, so all that's out there are poor quality fansubs.
- Name's the Same: Before 2011, if you said "Madoka" in anime fandom, you were talking about Ayukawa Madoka. After 2011 it was Kaname Madoka from Puella Magi Madoka Magica. The fact that both anime have characters named "Kyosuke" and "Akemi" does not help.
- No Dub for You: The TV series, the OVAs, and the first movie were released in North America on subtitled-only VHS and DVD by AnimEigo and later Blu-ray by Discotek Media. Averted with the second movie, which instead went to ADV Films, and released with a dub.
- One-Hit Wonder:
- This series is Izumi Matsumoto's only successful manga.
- Anne C. Mallory, who voiced Madoka in the English dub of the Summer's Beginning movie, has no other credits whatsoever.

- Pilot episode: Saeko Shimazu (Madoka), Yuu Mizushima (Kyōsuke), Yōko Ogai (Hikaru)
- TV series, OAV's and early radio dramas: Hiromi Tsuru (Madoka), Tōru Furuya (Kyōsuke), Eriko Hara (Hikaru). Additionally, Chieko Honda (Kurumi) and Michie Tomizawa (Manami), Maria Kawamura (Madoka's sister), Yoshiko Sakakibara (Madoka's mom), Kei Tomiyama (Takashi), Yumi Takada (Akemi), Naoko Matsui (Akane), Shigeru Nakahara (Shuu), Chiyoko Kawashima (Hikaru's mom), Keiichi Nanba (Komatsu), Naoki Tatsuta (Hatta), Kenichi Ogata (Jingoro), Chika Sakamoto (Kazuya)...
- Late CD dramas: Tomo Sakurai (Madoka), Ryō Horikawa (Kyōsuke), Yuka Imai (Hikaru), Yuko Miyamura (Kurumi) and Emi Motoi (Manami).
- Outlived Its Creator: Izumi Matsumoto, the manga's creator, passed away on October 6, 2020 at the age of 61.
- Relationship Voice Actor: Hiromi Tsuru and Tohru Furuya played Bulma and Yamcha, another couple, around the same time.
