Explain the term- fast-moving consumer goods

Marketing communications which are undertaken by organisations within these systems can be regarded as a series of communication episodes. These episodes can generally be construed as a dialogue and can be seen to be continuous. Amount of time between episodes may vary from the very small, like those associated with many major FMCG (fast-moving consumer goods) brand campaigns, which run and run, or very large, like those associated with some business-to-business campaigns or one-off events associated with a single task, like government drink-driving campaigns held annually every Christmas period.
