Alphabet Lore is an animated YouTube series by creator Mike Salcedo in which every letter of the alphabet is a character with its own design, voice and storyline. The series launched in 2022 and quickly went viral with younger viewers, spawning countless fan edits, compilations and a Number Lore follow-up. Short voice clips like J's became popular raw material for memes because each letter is instantly recognisable on its own. Creators still reuse them for spelling jokes, lore recaps and alphabet-themed videos across YouTube, TikTok and soundboards.
