sound bite

sound bite idiom
A short, striking, quotable statement well suited to a television news program. For example, He's extremely good at sound bites, but a really substantive speech is beyond him. This slangy expression, first recorded in 1980, originated in political campaigns in which candidates tried to get across a particular message or get publicity by having it picked up in newscasts.
