The awww reaction comes from the long tradition of recorded studio audiences on television sitcoms, talk shows and variety programs, where a crowd's sympathetic response guided viewers at home. Short isolated clips of that reaction later spread through meme soundboards, video editing packs and social media, detached from any single show. Creators now use it as universal shorthand for cuteness and tenderness, especially in fan edits, animal videos and reaction compilations, because the meaning is understood instantly across languages and needs no explanation or context to work.
