Off the air
Meaning
Not currently broadcasting or transmitting, often referring to a radio or television station that has stopped its regular programming.
Origin
The phrase "off the air" emerged directly from the advent of radio broadcasting in the early 20th century. Radio waves, invisible yet powerful, carried voices and music through the "air" from a transmitting antenna to receivers. When a station ceased its transmissions, often at the end of its broadcast day, it literally stopped sending signals through the air. This technical reality quickly entered common parlance, describing not just the literal cessation of a broadcast, but also, by extension, any temporary pause or ending of communication from a media outlet, solidifying its place as a staple of broadcasting terminology.
Examples
- The local radio station goes off the air every night at midnight, playing only an emergency broadcast test tone.
- After a long day of interviews, the news anchor was happy to finally be off the air and head home.
