TAG: - A local live or recorded addition to another pre-recorded announcement. An example would an announcer reading a live tag after a 25-second hardware spot saying: "There are 27 ACE Hardware Stores in the Greater Delaware Valley. ACE is the place for the helpful hardware man." Frequently the Traffic Director will be called upon to run the same announcement several times during the advertiser's campaign, but rotate several different tags to the main commercial announcement. For example a Sidewalk Sale at a Mall, 'tagged' with a rotating list of participating mall merchants each time the event is promoted. This type of rotating several different participating stores or dealers is known as 'ROTATING TAGS' and is very common in the local radio marketplace.

tag是标签，这里的意思是电台将那些买了广告时段的公司的广告做成签，轮流念，或弄成广告带，到时候插播就是了。
