Plim Plim is the signature ident sound of Rede Globo, Brazil's largest television network, where the short chime has marked commercial breaks and channel idents for decades. It became a piece of shared cultural shorthand: Brazilians recognise it instantly, and the jingle is endlessly parodied in comedy sketches, funk remixes and internet memes. As recognisable in Brazil as the Law and Order DUN DUN sting is abroad, it now works as a universal symbol for 'we are on television', which is why meme editors reach for it whenever a clip needs fake broadcast gravitas.
