The range of dates between which the advert schedule will schedule this campaign. It is still possible to manually schedule the campaign outside these dates.
The categories for which the advert campaign belongs. Categories can be used to prevent adverts of the same kind being played in the same advert block. For example, you would not want two competing fast food restaurants to be played in the same advert block. Adverts in advert campaigns with the same category will never be played in the same advert block.
The adverts that belong to this campaign. An advert represents a cut of audio that can be played at specified times of the day or week up to a maximum number of plays for the campaign.
