The term "sign off" originates from the early 20th century and is derived from the practice of radio broadcasters ending their programs by physically signing off on a logbook or logsheet. In the early days of radio, broadcasters were required to maintain a record of their transmissions for regulatory purposes. This logbook would contain information about the program, such as the time of broadcast, content, and duration. When the broadcast ended, the radio host would physically sign their name to mark the conclusion of the program. Over time, the phrase "sign off" became associated with the act of concluding a broadcast or ending a communication. Today, it is commonly used in various contexts, including radio and television broadcasting, as well as in general speech to signify the end of a conversation or message.
