Endcards are the short branded clips television channels use to close a programme and move viewers on to the next show, and E4 has long used distinctive idents as part of that on-air identity. Short clips like this one circulate on soundboards because creators want a recognisable broadcast ending without needing a full theme tune. At under two seconds, it is easy to drop into edits, compilations and social videos, where it works as a tidy sign-off that audiences already associate with television.
