Television stations have long used recorded sign off announcements when they leave the air for transmitter work or scheduled maintenance, and this clip follows that tradition for TXA21, the channel 21 station. Instead of a national anthem or closing ident, the message is purely practical, which is why it survives online as a soundboard clip. Shared as a short six second audio file, it is reused far from broadcast television, as a tidy, official sounding sign off for streams, videos, group chats and servers that are about to go offline.
