Dead air is a phenomenon whereby a broadcast which normally carries audio or video unintentionally becomes silent or blank (also known as unmodulated carrier). The term is most often used in cases where programme material comes to an unexpected halt, either through operator error or for technical reasons, although it is also used in cases where a broadcaster has 'dried up'. It is the duty of all concerned to rectify the problem as quickly as possible; in many parts of the world dead air is considered to be one of the worst crimes a broadcaster can commit.

Under British broadcasting laws, any radio station which transmits dead air for more than ten minutes without rectifying the situation, broadcasting an announcement, or warning its listeners, can be penalised or fined up to £25,000 per minute. The regulator for this used to be the Radio Authority, which has since become part of OFCOM, a unit of the British government. The Office of Communications, usually known as Ofcom, is the UKs communications regulator. ...
Dead air can also apply to television broadcasting, generally when a television channel has an interruption to its output, resulting in a blank screen or in the case of digital television, a frozen image, until output is restored or an apology message is broadcast. It has been suggested that Digital terrestrial television be merged into this article or section. ...
Having dead air during commercials or sponsorship announcements can cost networks considerable advertising revenue.

Another case was BBC Radio 4's failure to broadcast Big Ben's midnight chimes on New Year's Day 2003; after announcing the chimes, a technical error caused the station to fall silent for a minute. This was caused by the correct feed not being faded up. Ironically, the chimes were supposed to be coming via a new link which the BBC had just installed to Westminster just to avoid cases of dead air.
