!!For the books:
* CreatorsPest: Behold, [[https://bsc-snark.livejournal.com/39867.html evidence that Ann M. Martin has it out for poor Mallory.]]
* FanNickname: "K. Ron" (after L. Ron Hubbard) for Kristy and "[=BSCult=]" have become popular on some snark communities.
* KeepCirculatingTheTapes: A good portion of the series is out of print. An attempt was made at a reprint in TheNewTens but stopped at only a few books due to dismal sales.
* TechnologyMarchesOn: A big deal is always made of Claudia having her own phone line for them to use as the Babysitters Club number. Nowadays, most (if not all) of the girls would have cell phones.
* WhatCouldHaveBeen: A spin-off series called ''Morbidda Destiny, Teen Witch'' was considered, but scrapped when test audiences reacted poorly.

!!For the TV series:
* RetroactiveRecognition:
** A young Creator/ZachBraff plays Dawn's love interest in an episode of the TV show.
** Music-wise, the singer of the opening theme, Emily Bindiger, would later go on to collaborate with Music/YukiKajiura and provide vocals for a few of her soundtracks, such as ''Manga/PandoraHearts'' and ''Anime/ElCazadorDeLaBruja''.
